Best AI SDR Tools in 2026: AiSDR, Amplemarket, Artisan and 11x (Compared)
Compare AI SDR tools by research, sending, replies and booking. Verified prices, required inputs, human review and cost-per-meeting scenarios.

The best AI SDR tools for a 5 to 50-person company are the ones that take ownership of the work you need to delegate: AiSDR starts at $250 a month for a small full-workflow pilot, while Amplemarket starts at $600 a month on an annual term for two people who stay in control. Choose an autonomous agent when you can oversee a delegated prospecting and reply workflow; choose a copilot when a rep will approve outreach and own the conversation.
Best AI SDR Tools at a Glance
AiSDR is the starting choice for a founder who wants to delegate a small outbound workflow without an annual commitment. Reply.io's Jason is the alternative when you want explicit message and reply approvals with more contact capacity. Amplemarket is the stronger fit when you already have sellers and want to improve their research and outreach rather than hand their conversations to an agent.
The order below groups tools by how much of the SDR job they can own. The first four document research, writing, sending, reply handling and booking. Amplemarket keeps a rep in the workflow; Apollo supplies a rep-operated prospecting and engagement platform. More autonomy does not automatically make a tool the better purchase.
Prices and plan details were verified against the vendors' live pages on 2 October 2026. An annual monthly equivalent is a budgeting figure, not a month-to-month cancellation right. Taxes, mailbox purchases, add-ons and human oversight can change the total.
AiSDR and Amplemarket have partner relationships with this site. They receive the same coverage checks and candid limitations as the other products. This comparison verifies published capabilities and prices; it does not claim a live outbound test or treat a vendor's meeting-rate claim as an observed result.
AI SDR Meaning: Delegate Five Jobs, Keep One Owner
An AI SDR is software that takes on some of the work of a sales development representative, the person who finds potential buyers and starts conversations before a closer takes over. The buying question is which tasks it owns after you finish setup.
The job has five parts:
- Research and list building: Find companies and people who fit, verify contact details, and establish a reason to reach out.
- Writing: Turn that reason and your offer into an opening message and useful follow-ups.
- Sending: Deliver the sequence through connected accounts, pace activity, and stop contacting people who reply or opt out.
- Handling replies: Understand a buyer's response, answer within your approved knowledge, and route exceptions to a person.
- Booking: Move an interested, suitable prospect onto the correct calendar with the context a seller needs.
Your ideal customer profile, or ICP, describes who is likely to buy. A useful ICP specifies company characteristics, the relevant role, the problem you solve and exclusions. A database filter for a job title is only part of it.
Suppose you sell software that fixes a specific operational problem. Research should establish that the problem is plausible at the target account. Writing should connect your offer to that evidence. A reply asking about an unsupported integration should reach someone who can answer it. A booked meeting should include the original reason for interest. Automating the opening email alone does not accomplish that chain.
You still need one accountable owner. That person approves the offer and target, checks samples, handles exceptions and decides whether the meetings deserve a seller's time. Removing repetitive work is useful. Removing responsibility is how a cheap subscription becomes an expensive distraction.
Which Parts of the SDR Job Are Automated?
Reply handling is the cleanest dividing line between a delegated SDR workflow and an assisted sales tool. Drafting an email, labeling a response as interested, and negotiating a suitable meeting are different functions.
AiSDR: Research and list building, personalized writing, sequences, reply handling or co-pilot review, and calendar integrations are documented. Its practical limits are the researched-contact allowance, sender resources, CRM tier and the quality of your setup.
Reply.io Jason: Lead sourcing, prospect research, multichannel writing and sending, automatic or approval-based replies, and calendar booking are documented. Call steps create tasks and scripts for a person; they do not establish autonomous telephone selling.
Artisan Ava: Sourcing, personalized sequences, sending, replies and booking are documented. You can choose approval controls per campaign. Your reps still make calls through the separately scoped dialer.
11x Alice: Its documentation covers the full outbound chain, with managed sending infrastructure, configurable replies and escalation. That scope comes with a substantial annual commitment and a public pricing disagreement that needs a written quote.
Amplemarket Duo: Signals, research and multichannel outreach preparation support a rep who reviews and acts. Duo Inbox generates draft replies on eligible plans. Budget a person to own buyer conversations and booking.
Apollo: Contact data, AI research, sequence creation, scheduled sending and reply sentiment analysis support a human seller. Its documented email workflow has the person compose and send the reply. Scheduling features should not be confused with autonomous objection handling and booking.
These are capability classifications. They do not tell you which product will book more meetings for your offer. A tool can cover every stage and still target the wrong people; a human-led workflow can cover fewer stages automatically and produce better conversations.
The Tools, Sorted by Job Ownership
The full-workflow group comes first, followed by the copilot and rep-operated options. Within the full-workflow group, the order favors a small-company buying decision: an accessible pilot, explicit controls, then the more heavily scoped commitments.
1. AiSDR: A Small Full-Workflow Pilot With a Published Price
AiSDR is an AI outbound platform that documents the whole path from lead research to replies and booking, and its $250 Solo plan makes it the lowest-priced full-workflow starting point on this shortlist. It fits a founder with a narrow offer who wants to delegate execution while retaining responsibility for targeting and buyer-facing claims. Its named wall is capacity: Solo provides 200 AI-researched contacts per month and one user. That makes it a focused pilot, not unlimited outbound for a sales department.

Best for: A founder proving one delegated outreach motion on a small target segment.
Standout: Research, sending infrastructure and reply handling inside one workflow, with co-pilot review available.
Pricing: Solo $250/mo; Explore $900/mo; Scale $2,500/mo. Annual totals are $2,400, $8,640 and $24,000 on the live plan page.
Free trial: Signup and campaign building without a card; the paywall appears when you are ready to launch.
The current AiSDR pricing page measures capacity in AI-researched contacts, defined as net-new leads it finds, qualifies, enriches and adds to campaigns. That is a more useful unit than raw sends, but it still measures inputs. A researched contact has not agreed to meet you, and several messages to the same contact do not create several prospects.
Solo lists one domain, three mailboxes and one LinkedIn account. Explore raises the allowance to 800 researched contacts, two domains, six mailboxes and five LinkedIn accounts, with unlimited users. Scale lists 2,500 researched contacts, six domains, 18 mailboxes and 20 LinkedIn accounts, also with unlimited users. Those resource counts determine the workflow you can run; they are not promises of a particular sending pace or outcome.
The CRM boundary matters. Solo lists native two-way HubSpot sync. Native two-way Salesforce sync appears on Scale. A company organized around Salesforce should price the plan that names that integration rather than assume the lowest card includes it. Explore also adds support for existing lead lists and GTM engineer onboarding. An existing list can be useful, but you still need to remove customers, active opportunities and accounts someone else owns.
AiSDR documents live lead search, web-based research, enrichment, personalized email and LinkedIn sequences, objections and questions handling, and replies or co-pilot mode. It lists Calendly and HubSpot calendar integration. The coverage is broad enough to delegate the operational chain. Your job is to give it a defensible offer and decide what it may say when a buyer asks for more.
What it needs from you: Your website and product explanation, a precise target, exclusion lists, a genuine example of your sales writing, approved answers, calendar routing and CRM access where used. A purchased list is optional because prospecting is included. If you need sending domains, the page says AiSDR can obtain and set them up; mailbox creation, warmup, rotation and domain-health tracking are listed. Confirm ownership and continuing costs on the order before launch.
Where a person reviews: Approve the target and generated strategy, inspect the proposed messages, and use co-pilot handling while the reply knowledge is being calibrated. Keep discounts, unusual technical questions, security promises and strategic accounts with a person. An agent that can respond quickly should still be allowed to say that a colleague needs to answer.
Choose the Commitment Before the Capacity
Solo runs month to month. Explore and Scale are billed monthly on quarterly contracts, according to the plan page. Their base quarterly commitments therefore work out to $2,700 and $7,500. The displayed annual totals correspond to $200, $720 and $2,000 per month respectively, but those are annual-plan equivalents. Confirm invoice timing and termination conditions rather than reading broad “cancel anytime” copy as a refund promise.
The base price also differs from a managed-service price. Explore advertises optional service at an additional $149 per campaign, with the fee cadence to confirm. Scale advertises a fully managed option at an additional $2,500 per month. That would make Scale plus that service $5,000 per month before other incremental costs.
A Practical AiSDR Pilot
Start with a segment whose offer and objections you already understand. The platform's setup flow asks for your site, mailboxes, CRM and suppression lists, a sample email, and a strategy review. Treat each as a decision, not an onboarding form to rush through.
Define one offer and one target
Write the problem, relevant role, qualification criteria and exclusions. Give the agent a genuine email example and approved product information.
Prepare sending and suppression
Use dedicated sending domains, confirm authentication and warmup with the provider, and exclude customers and existing opportunities before adding prospects.
Inspect a sample before launch
Review a proposed 20-contact sample as an operating check. Verify the reason for contact, the research evidence and every claim in the message. Correct the setup if errors repeat.
Keep replies under review first
Start with co-pilot handling and a named person responsible for exceptions. Count unique meetings in the CRM and record whether they held and qualified before expanding the program.
- Published entry price with a month-to-month Solo option.
- Research, sending setup and reply handling are documented in the same platform.
- Co-pilot mode provides a way to retain reply review.
- Prospecting can start without an externally purchased list.
- Solo has one user and a small researched-contact allowance.
- Explore and Scale require quarterly commitments despite monthly billing.
- Native Salesforce sync is listed on Scale, which changes the entry budget for that CRM.
- Managed service can materially increase the base subscription.
Verdict: Choose AiSDR Solo to learn whether delegating a narrow outbound workflow helps your business. Skip the entry plan when several sellers, Salesforce sync or a much larger researched list are requirements from the start.
2. Reply.io Jason: Full Workflow With Explicit Reply Approval
Reply.io's Jason is an AI sales agent that documents lead search, research, outreach, replies and meeting booking, with separate approval controls for messages and responses. It suits a sales lead who wants to delegate execution but inspect how the agent speaks to buyers. The budget boundary is the dedicated AI SDR plan: Starter begins at $800 month to month for 1,000 active contacts, or $500 per month billed annually. The cheaper ordinary Reply sequencer price does not establish the price of this full workflow.

Best for: A small sales operation that wants an agent with visible research sources and reply approvals.
Standout: Automatic replies or approval-required replies, plus source links to inspect personalization.
Pricing: AI SDR Starter from $800/mo monthly or $500/mo annual; Growth from $2,500/mo monthly or $1,500/mo annual; Enterprise custom.
Free trial: Reply advertises a general 14-day trial; confirm that the offered trial includes the Jason workflow you need.
Jason's product page explains the useful distinction between automatic mode, which sends the AI's response, and approval mode, which generates a reply for you to approve. It also describes reviewing each outbound message with its research context. That is a meaningful purchase criterion when a buyer's reply could require a delicate answer.
For example, a prospect might ask whether your software works with an unusual existing system. The agent's speed is less valuable than whether it cites an approved answer or hands the conversation to the right person. A sales lead can use approval mode to identify repeated knowledge gaps, then decide which bounded questions are suitable for automatic handling. Approval is an operating control, not evidence that any particular answer will be correct.
Jason can search for leads from a plain-language target, research LinkedIn and company sources, and accept your own account list. Its documented inputs include an offer, playbooks, company information, product details and objection materials. The platform also describes automatic booking from connected Google Calendar availability. The calendar can supply open slots; your instructions must establish who should receive those slots and which seller owns them.
What it needs from you: A product knowledge base, approved messaging and objections, targeting and exclusion rules, calendar access, and sender/LinkedIn accounts as applicable. A finished contact list is optional, but an account list helps when your market is specific. Domains and mailboxes still need an owner. Ask which provider subscriptions and provisioning costs are in your order.
Where a person reviews: The documented message and reply approval modes allow direct review. Human call steps remain human: Jason can add tasks and generate scripts, but those features do not mean it makes sales calls for you. Budget the rep who will action them.
Every Jason Contact Tier, With Billing Made Explicit
The dedicated AI SDR tab on Reply's live pricing page and its linked structured pricing file agree on these options:
- Starter, 1,000 active contacts: $800/mo monthly or $500/mo annual.
- Starter, 2,000: $1,200/mo monthly or $800/mo annual.
- Starter, 3,000: $1,500/mo monthly or $1,000/mo annual.
- Growth, 5,000: $2,500/mo monthly or $1,500/mo annual.
- Growth, 10,000: $5,000/mo monthly or $3,000/mo annual.
- Enterprise, 25,000 or 50,000: Custom quote.
An active contact is a unique person you can send a first-step email and subsequent follow-ups to during the month. It is not a researched-contact unit identical to AiSDR's, and it is not a booked meeting. Ask how a continuing sequence uses the allowance across billing periods before forecasting your list consumption.
Starter and Growth list unlimited users, autopilot and copilot modes, multichannel automation, mailbox connections and warmups, onboarding and deliverability service. The exact sender and channel resources still belong on your order. Unlimited connections are not unlimited free mailbox subscriptions.
The pricing page also contains a generic “Hire Jason” teaser starting at $500, including under the monthly Sales Outreach view. The dedicated monthly AI SDR Starter option is $800. Use the dedicated plan option for the monthly buying decision; the teaser does not establish an $800 workflow at a $500 monthly cancellable price.
Reply's ordinary sales-engagement subscriptions are a separate buying option: Email Volume starts at $59/user/mo monthly or $49/user/mo annual; Multichannel starts at $99/user/mo monthly or $89/user/mo annual. They may suit a rep-operated process. Do not attach their entry price to every Jason capability. Agency Core, Agency AI SDR and Hybrid plans address a different, multi-client purchase.
- Documented approval modes for both outreach and replies.
- Research source links help a reviewer check personalized claims.
- Lead search, reply handling and calendar booking cover the full operational chain.
- Several contact-volume choices avoid forcing every buyer into an enterprise quote.
- The annual teaser and monthly AI SDR price can be confused.
- Provider mailboxes and domains can add costs beyond connection allowances.
- Call tasks still require someone to make the call.
- A general Reply trial does not prove a free Jason sending trial.
Verdict: Choose Jason when explicit review controls and its contact capacity fit your motion. Skip it when you only need scheduled sending, or when the annual discount is the sole reason you are considering a larger commitment.
3. Artisan AI SDR: Full-Workflow Automation With a Custom Quote
Artisan's Ava is an AI business development representative, or BDR, that documents lead sourcing, personalized outreach, replies and booking with campaign-level approval controls. It belongs on the shortlist for a company that wants a scoped outbound rollout rather than another tool for a rep to operate manually. Its commercial wall is visibility: the current Team, Scale and Enterprise cards all require a custom quote. A budget taken from an old advertised starter price is not a budget verified against today's plan page.

Best for: A company with a proven target and enough outbound work to justify a vendor-scoped implementation.
Standout: Full-workflow execution with campaign-specific control over sending and targeting.
Pricing: Team, Scale and Enterprise are custom-quoted; dialer seats are an add-on.
Free trial: Free to start exploring is stated; no defined free live-sending allowance is verified here.
The Ava product page documents sourcing from Artisan's B2B data, prospect enrichment, intent signals, personalized multichannel sequences, reply handling and scheduling. It also lists review controls for outreach, targeting changes, reply thresholds, routing and pausing. The breadth earns Ava a place in the full-workflow group. It does not establish how well those functions will perform for your business.
An appropriate buying situation is a company whose sellers already know which accounts buy and which objections recur, but cannot keep the top of the funnel moving. Give Ava that defined motion and let the implementation discussion establish the remaining operational work. If the offer changes every week, the problem is still discovering what to sell and whom to sell it to; a broader automation contract will amplify that uncertainty.
Ava AI BDR: What You Supply and Approve
You supply the ICP, offer, exclusions, approved knowledge and sender identity. Artisan's pricing FAQ says Ava sends in your reps' names from your own sending domains. Its rollout includes sending infrastructure sized to the motion. That does not make the ownership, ongoing provider bill or replacement policy irrelevant: put them in the quote.
A finished list is optional because sourcing is documented. Your own account data can come through custom webhooks, and the page lists bi-directional Salesforce and HubSpot sync. The data advantage only matters if the records match your market. Ask the vendor to show a proposed sample of your target accounts and explain why they qualify before authorizing the full list.
Your approval policy can differ by campaign. A broader, lower-stakes segment may eventually permit automatic sending. A named-account campaign can keep approvals on. Ava's controls should be configured around the consequence of a wrong message, not merely around how many messages a person can review.
Where a person reviews: Approve initial targeting and claims, retain review for important accounts and sensitive answers, and give escalations a named destination. The platform documents per-campaign approval rather than requiring one permanent autonomy setting for every segment.
The phone distinction deserves a direct line: Ava does not make the sales calls. The product page describes preparing qualified prospects and context for reps to dial, while pricing lists a dialer add-on per seat. A dialer can assist a person without being an autonomous voice SDR. If telephone conversations are the bottleneck, ask who performs them and include that labor in the comparison.
Artisan AI Pricing: Team, Scale and Enterprise
The current plan page presents:
- Team: Approximately 2,500 leads contacted per month; custom price.
- Scale: Approximately 6,000 leads contacted per month; custom price, with dedicated customer success, CRM setup and priority support.
- Enterprise: Custom volume and price, with a strategist, rollout buildout and additional security controls.
Every plan lists the platform, autonomous replies and booking, B2B data, CRM sync, support and onboarding. The quote depends on lead volume, mailboxes and dialer seats. The lead counts are approximate plan-sizing cues, not precise meeting capacity.
For a small company, the purchase should specify both the dollar amount and the unit. Is a contacted lead counted once in the term, once in the month, or again on reactivation? Which sender resources are funded? What happens when a campaign pauses? The public page does not settle every procurement detail, so let the signed quote settle it before comparing Artisan's cost to a cancellable entry subscription.
- Documented sourcing, outreach, replies and calendar booking.
- Approval settings can differ by campaign.
- CRM sync and custom data inputs support an existing sales operation.
- Rollout support is part of the plan rather than an unexplained setup task.
- No verified public dollar price on the current Team, Scale or Enterprise cards.
- Approximate contacted-lead bands need contractual definitions.
- Sender-domain ownership and provider costs need an explicit order.
- Reps still make calls, and dialer seats are separately scoped.
Verdict: Evaluate Ava when you can give it a proven motion and obtain a complete quote. Skip it when you need a transparent, small subscription to discover whether outbound works at all.
4. 11x Alice: Broad Delegation With Managed Sending Infrastructure
11x's Alice is an outbound digital worker that documents research, personalized outreach, replies and meeting booking, backed by managed Gmail mailboxes and domain setup. It fits a company that wants to delegate the infrastructure as well as the outreach process. The buying wall is commitment: Growth's card and current help documentation start at $3,750 per month billed annually. That implies a $45,000 annual base, and the price page's FAQ gives a conflicting figure that must be resolved in the quote.

Best for: An established outbound motion whose budget supports a managed annual deployment.
Standout: Sending infrastructure and full-workflow execution, with documented reply simulation and escalation.
Pricing: Growth from $3,750/mo annual; Pro and Enterprise custom. Confirm the public annual-price conflict in writing.
Free trial: No public self-serve free-trial term confirmed on the pricing sources used here.
Alice's overview describes identifying and researching prospects, writing personalized messages, running sequences, classifying replies and booking meetings. Its source and qualification functions can reduce the list work your company performs. The knowledge base and ICP are still inputs you own, and they shape what the worker does.
The pricing page lists managed Gmail mailboxes, domain setup, warmup, inbox rotation, monitoring, bi-directional CRM sync and onboarding. That bundle makes a comparison to a bare sequencer misleading: a sequencer's lower price may omit tasks and subscriptions the 11x quote includes. It also makes a comparison to a loaded human SDR incomplete if you ignore the manager who still supervises targeting, replies and quality.
What it needs from you: A defensible ICP, product and positioning knowledge, approved claims, exclusions, calendar/rep routing and your CRM license. A purchased list is not a prerequisite for documented prospecting. Verify domain ownership, sender names, access and what happens to those assets if you leave.
Where a person reviews: The brand-protection documentation describes reviewing every message, a named approval workflow, or autopilot. The Smart Replies documentation goes further: handling can be automatic, skipped or escalated by reply category, and simulation lets you review drafts before automatic responses are enabled.
That is useful for a sales lead who wants to automate simple information requests while keeping procurement discussions with a person. Simulation can expose a knowledge gap before a buyer encounters it. An approved response to “What does your product do?” does not establish permission to answer “Will you contractually guarantee this security requirement?” Configure those separately.
Alice's Three Plans and the Price Disagreement
Growth lists up to five end users and 2,000 new prospects per month. Pro is custom-quoted with up to ten users and 5,000 new prospects. Enterprise is custom-quoted with unlimited users and 10,000 or more new prospects. Do not extrapolate the Growth price linearly to the higher plans; their quotes also buy different scope and support.
The pricing card says $3,750/mo billed annually. The same page's FAQ says $36,000/year. Current 11x pricing documentation repeats the $3,750 card basis. Multiplying that monthly equivalent by a year produces $45,000, not $36,000. This comparison uses the agreeing card and help-document basis for budgeting and leaves the signed invoice price unresolved.
The help documentation says annual billing is the default and there are no setup or implementation fees. Alice's email infrastructure is bundled; your CRM license is separate. Alice is also priced separately from Julian, the inbound product. An inbound call or chat demo does not establish what the outbound Alice order includes.
At full Growth capacity, the $3,750 card basis allocates $1.875 per listed new prospect. That is an allocation of the subscription, not a contact purchase price or an outcome cost. If the right target universe is small, unused capacity makes that calculation less useful, while the annual commitment remains.
- Documented full outbound coverage and managed sending infrastructure.
- Reply simulation provides a concrete review step before automatic responses.
- Per-category escalation can preserve human handling for difficult conversations.
- Published Growth scope makes initial capacity easier to compare than a wholly undisclosed quote.
- Annual commitment is substantial for a small-company experiment.
- Pricing card and FAQ disagree on the annual dollar amount.
- Pro and Enterprise require quotes; Growth cannot price their scope.
- A separate inbound product should not be assumed part of the Alice subscription.
Verdict: Choose Alice when the managed infrastructure and delegation solve an established operational problem at a defensible annual cost. Avoid making it your first attempt to prove an ICP or offer, and do not sign while the annual-price conflict remains unresolved.
5. Amplemarket Duo: A Copilot for Sellers Who Own the Conversation
Amplemarket is a sales intelligence and engagement platform whose Duo Copilot finds signals, prepares research and drafts multichannel outreach for a rep to review. It fits a founder and seller who need better inputs and a more consistent outbound workflow while keeping control of buyer conversations. Startup starts at $600 per month on an annual term with two users. The key wall is reply scope: Duo Inbox produces draft replies, and it is not listed on Startup.

Best for: Sellers who have time to review outreach and work interested replies.
Standout: Contact-level signals, research context and suggested sequences inside one rep-controlled platform.
Pricing: Startup $600/mo annual term, two users; Growth and Elite custom.
Free trial: The live plan page offers one on all plans; its duration is not published there.
Duo's documented workflow surfaces people based on buying signals, gathers context and prepares personalized sequences. Reps can review, edit, regenerate or send the proposal. It learns from dismissals and edits. That gives a seller a prepared starting point without making a machine's initial judgment the final word on who receives a message.
For a founder and first sales hire, that arrangement can be valuable. The founder knows the product and can check claims; the seller can work the buyer conversation. Both can benefit from better research. If neither can review the queue or respond when someone is interested, the copilot has not removed the missing job.
Amplemarket's platform includes contact/company search, enrichment, email validation, sequences and deliverability tools. It is therefore more than a writing add-on. Its scope is still different from buying unattended reply negotiation. Automatic sequence delivery after approval should not be mistaken for autonomous ownership of every later conversation.
What it needs from you: Sender access, domains and mailboxes or a separately priced setup, a target definition, territory/account ownership rules, exclusions and CRM context. A finished list is optional because the platform provides search and signals. Budget a human to review recommendations and handle replies through booking.
Where a person reviews: Review the recommended prospect and why the signal matters, verify the outreach, and decide whether to launch it. A signal such as a job change can be accurate without making your offer relevant. The rep must connect the evidence to a plausible business problem. Keep the buyer conversation owned by that rep.
Startup, Growth and Elite Are Different Purchases
The live pricing page publishes Startup at $600 per month on an annual term with two included users. That is a $7,200 annual base, or $300 per included user-month when both use it. A solo founder pays the same base while leaving an included user unused.
Growth includes four users and is custom-priced; Elite includes ten and is custom-priced. Additional users are available, but the public page does not disclose their unit price. Do not double Startup to estimate Growth or multiply it to estimate Elite.
The current email and phone credit allowances are separate:
- Startup: 13,500 email credits and 600 phone credits per user per year.
- Growth: 35,000 email credits and 5,000 phone credits per user per year.
- Elite: 40,000 email credits and 9,600 phone credits per user per year.
Startup's two-user totals are 27,000 email credits and 1,200 phone credits annually. Averaging the email allowance over the year gives 2,250 per month, but that is a budgeting average, not a promise of a monthly grant. Neither pool is an entitlement to researched, qualified or interested prospects.
Duo Copilot and Copywriter are listed on Startup. Voice appears on Growth and Elite. Duo Inbox is an add-on on Growth and included on Elite, rather than a Startup feature. Its description is automatic draft replies. A person still needs to review or act on those drafts; the description does not establish automatic response sending and calendar negotiation.
This feature gate is why Amplemarket belongs in a different group from the full-workflow agents. A sales lead may prefer that ownership structure. They should buy it deliberately rather than expect the Startup subscription to become an unattended SDR after setup.
The Amplemarket pricing breakdown goes deeper on included users, the separate credit pools, extra-seat questions and the buying sheet. Use it to request a complete quote when Startup's public floor does not describe your required setup.
- Research, signals and sequencing sit inside a rep-controlled workflow.
- Startup publishes a price and included-user count.
- Built-in search and enrichment can reduce separate data work.
- Reviews and feedback remain part of how the copilot operates.
- Startup requires an annual term and includes two users even if only one is active.
- Duo Inbox is not on Startup and is only a draft-reply function as described.
- Growth, Elite, extra users and some AI capacity require a quote.
- Human reply handling and booking remain work to fund.
Verdict: Choose Amplemarket when improving an existing seller's workflow is the goal. Skip it as a replacement for the person who answers interested buyers, especially if the buying plan is Startup and the expected feature is Duo Inbox.
6. Apollo: Lower-Cost Prospecting With Human Reply Ownership
Apollo is a sales intelligence and engagement platform that combines contact data, AI research, outreach creation, sequences and pipeline tools for a human seller. It is the economical starting point when a founder can still run the conversations and wants help building and working the list. Basic is $49 per seat per month on annual billing. Its documented reply workflow remains a human workflow, so that price should not be compared to full agents as though the delegated labor were identical.

Best for: A founder or seller who will work replies and use automation for preparation and sending.
Standout: Contact data, AI-assisted outreach and sequences at a lower subscription floor.
Pricing: Free $0; Basic $49/seat/mo; Professional $79/seat/mo; Organization $119/seat/mo with three seats minimum. Paid rates shown are annual, corroborated in Apollo's plan details.
Free trial: 14 days on Basic and Professional, with a continuing Free option.
The current pricing page lists AI research and an AI Assistant, sequences and scheduling features. The assistant is labeled introductory, so confirm its ongoing terms before attributing permanent value to the present bundle. Apollo also offers monthly billing; the annual prices above should not be read as verified monthly cancellable prices.
Apollo's outreach documentation describes selecting prospects, asking the assistant for a sequence, reviewing the result and confirming the action. Scheduled agents can recommend and prepare campaigns, but the documented workflow still includes review before sending. That is a good fit when a founder knows the offer and needs preparation to take less time.
The distinction after a reply is explicit. Apollo's email documentation describes sentiment filters, then opening the thread, composing the response and choosing Reply now or Schedule. By default, a reply finishes that contact's sequence and stops the remaining steps. That prevents an unnecessary follow-up, but a stopped sequence has not answered the buyer or booked the meeting.
What it needs from you: Your offer and target, context for the assistant, connected sender mailboxes, suppression rules and a person to operate the reply queue. You do not need to arrive with a purchased contact list because data search is part of the platform. You do need to decide which results are suitable for your offer rather than export a broad title filter and assume it is an ICP.
Where a person reviews: Review suggested sequences and workflow changes, work the replies, qualify interest and arrange the meeting. A calendar link or meeting event can make scheduling easier after interest exists. It does not establish autonomous negotiation of a difficult answer.
Every Published Annual Tier, Plus the Seat Floor
Free lists 900 credits per seat per year, granted monthly. Basic lists 30,000 annually; Professional 48,000; Organization 72,000. Credit consumption can include data and research activity, so these are not interchangeable with the active-contact or researched-contact units in the agents above.
Basic offers unlimited sequences, core integrations and a deliverability suite with warmup on its current card. Professional adds more capacity and features; its card includes Agents. Organization adds organization-level controls and has the three-seat minimum. Do not choose a plan because the word “agent” appears: ask which actions the specific agent performs and who handles the replies.
The scheduling counts provide another easy misunderstanding. The plan cards list one meeting event on Free, three on Basic, six on Professional and unlimited on Organization. These are scheduling feature allowances, not a limit or guarantee of one, three or six booked sales meetings.
Apollo says every seat in an account must use the same plan. Two Basic seats therefore cost $98 per month equivalent or $1,176 annually. Two Professional seats cost $158 equivalent or $1,896 annually. Organization's minimum three seats cost $357 equivalent or $4,284 annually before extras. A requirement held by one seller can affect the whole account's plan choice.
Domain and mailbox purchasing are listed on the paid cards. That confirms availability of a purchase workflow, not free sender subscriptions. Credit top-ups also recur until removed, and unused credits expire at the billing-cycle boundary. Watch the human and usage costs alongside the low seat price.
- Free entry and published annual prices for all visible core tiers.
- Data, research and outreach preparation can live in one platform.
- Reply sentiment filters and default sequence stopping support a human reply queue.
- Paid cards now list warmup and deliverability tools as well as mailbox purchasing.
- The documented reply workflow needs a person to answer and book.
- Annual seat prices are not month-to-month cancellation rights.
- All account seats use the same tier, and Organization has a minimum.
- Credits, recurring top-ups and sender purchases add planning work.
Verdict: Choose Apollo when a person will own sales conversations and the main missing work is prospecting and outreach preparation. Skip it as an unattended meeting-booking employee on the strength of the Basic price alone.
Cost per Booked Meeting: What Can Be Calculated?
This comparison verifies subscription prices; it does not establish measured booking rates for the same audience, offer and period. A vendor's average meeting-rate claim does not supply the missing evidence for your offer.
There are two useful calculations. The first asks what the subscription would cost if it produced a given number of bookings. The second divides your full operating cost by the bookings recorded in a clean company-owned cohort. Only the second becomes a measured business result.
Subscription-Only Scenarios, Not Predicted Results
The following uses the same hypothetical denominators, ten or 25 unique booked meetings in a month. It excludes human time, taxes, extra data, additional domains/mailboxes and other tools. It also compares different capacity units and commitments, so it is a sensitivity check rather than a value ranking.
None of these denominators is a forecast. A lower result in the last column does not mean a tool can generate 25 meetings from its entry allowance. Apollo's inexpensive row also leaves more of the conversation work with you. 11x's row uses the card and help-document basis discussed above, pending the written quote.
Jason's $500 annual Starter equivalent would produce $50 or $20 in the same hypothetical calculation. That explains the effect of annual pricing; it does not establish a conversion advantage over the monthly subscription.
Measure the Full Workflow
Use this operating formula:
Cost per booked meeting = (subscription + sender/data extras + human review and reply labor + allocated setup cost) / unique attributable bookings.
Allocate annual subscriptions to the same period as the outcome, and keep a separate record of the cash commitment. Include human time even if the founder performs it without a salary transfer. A workflow that requires the founder's evenings consumes a resource the subscription invoice cannot show.
For a hypothetical AiSDR Explore ledger, assume $900 in subscription plus seven hours of human review and reply work at an assumed $50 per hour, with no other incremental costs. That totals $1,250. If the CRM records ten unique bookings, the cost is $125 per booked meeting. If seven hold, it is $178.57 per held meeting. If four meet your qualification standard, it is $312.50 per qualified meeting. These are worked assumptions, not AiSDR results.

For the same hypothetical $1,250 budget, a $150 ceiling per booking requires at least nine bookings. Eight would cost $156.25 each; nine would cost $138.89. Set the ceiling from your sales economics before the pilot rather than inventing a target after the dashboard looks encouraging.
Bookings need a company-owned definition. Deduplicate reschedules. Exclude internal tests. Record the prospect and account, campaign, first meaningful response, meeting date, attendance and qualification. An interested reply is not yet a booking; a booking that never happens is not yet a sales conversation.
Keep pilot accounts separate from those a human SDR or another campaign is already working. Otherwise both motions can claim the same meeting. The AI SDR versus human SDR cost-per-booked-meeting playbook develops the account-split and attribution problem. Use that method to measure your program; do not import someone else's historical outcome as a forecast for a new vendor.
Deliverability Basics Before Any Agent Sends
Sending infrastructure determines whether the outreach can reach a buyer; an AI-written message does not override mailbox-provider rules. Assign an owner to domains, authentication, sender limits and failure monitoring before launch.
Separate Sending Domains
Use dedicated sending domains for cold outreach so campaign activity is not concentrated on the domain used for invoices, customer conversations and operational mail. Make the sender identity clear and the domain recognizably yours. Separation reduces shared exposure; it does not guarantee that reputation problems cannot affect the business or that messages reach inboxes.
If the vendor provisions domains and mailboxes, establish who owns them, who can access them, who pays renewals and what transfers when you cancel. If you bring existing senders, verify their health rather than assume their age makes them suitable. A bundled setup is a task someone else performs, not a reason to skip the check.
Authentication and Warmup
Set up SPF, which identifies authorized sending services; DKIM, which signs mail so recipients can verify the sending domain; and DMARC, which adds alignment and a policy for messages that fail authentication. Google's sender guidelines recommend all three and explain the requirements that apply to different sender volumes.
Warmup means gradually establishing sending activity and observing delivery before increasing volume. It is not a timer that makes an inbox safe when it reaches a particular day. Google's guidance calls for gradual, consistent increases and reduced volume when bounces or deferrals appear. A vendor's warmup feature or pre-warmed inbox is not an inbox-placement guarantee.
Authentication is necessary but does not make an unwanted message welcome. Google also advises against mailing people who did not subscribe. Review the mailbox provider's policies and the intended recipient relationship, and make opt-outs easy. A tool's ability to send does not establish permission to contact a particular person.
Daily Limits Must Include Follow-Ups
For an initial pilot, a proposed operating cap is 20 total campaign emails per mailbox per day, including follow-ups, after the setup and warmup have been approved. This is a conservative planning setting, not a universal safe rate or a provider allowance. Follow any lower vendor or mailbox-provider limit and reduce or pause when monitoring deteriorates.
Four mailboxes at that proposed cap support 80 total campaign messages a day. If half are follow-ups, only 40 are first touches. That simple allocation explains why contact allowances and daily sender capacity should be planned separately.
Do not assume a provider's maximum account limit is an appropriate outbound target. Provider throttling can override the application's settings, and sudden jumps can damage delivery. Add capacity only after checking delivery responses, complaints and the quality of the remaining target list.
Monitor Delivery, Not Just Opens
Check bounces, deferrals, mailbox health and opt-outs; suppress people who ask not to be contacted across every campaign. For Gmail traffic, Google recommends keeping Postmaster spam rates below 0.10% and never reaching 0.30% or higher.
Google cannot verify third-party open-rate accuracy, and low opens do not reliably establish inbox placement. Use provider responses and buyer behavior alongside the dashboard. If you only need the sending layer, the AI cold email tools comparison covers that separate purchase; verify the current plan at the vendor before buying.
Where a Person Still Reviews
A person reviews wherever a wrong answer can change the deal, the relationship or the promise your company makes. Automation settings should reflect those consequences.
Before launch, review the target criteria, exclusions, sender identity, research sample, first message, follow-up logic and the claims in the knowledge base. A personalized line deserves inspection if it implies knowledge you do not have. Correcting a mistaken company fact is useful; correcting the instruction that keeps producing the mistake is better.
At first, review every reply. Keep discounts, contract terms, security assurances, delivery promises and unsupported integrations with a person. Also route strategic accounts, existing customers, angry replies and explicit requests for a human to that owner. Do not make the agent infer these boundaries from what you failed to include in the product description.

The products provide different ways to enforce that policy. AiSDR documents co-pilot handling. Jason documents reply approval. Ava documents campaign controls. Alice documents simulation and category-based escalation. Amplemarket and Apollo already retain human action in the documented workflow. Confirm the exact controls in the plan you are buying.
Finally, test the destination. An exception marked as escalated but delivered to an unwatched inbox is still an unanswered buyer. Assign a person, a place to receive the thread, and a response expectation that matches your operating hours. Only remove a review step when you have evidence that the remaining boundary is reliable.
AI SDR Companies: Who Should Pick What?
Choose on ownership of the buyer conversation first, then on capacity and commitment. That decision flips the recommendation more often than the length of the feature list.
You want a small delegated-workflow pilot: Start with AiSDR Solo if one user, its researched-contact allowance and the listed CRM scope fit. Move up only when the pilot proves a need for more capacity or a named feature.
You want an agent but insist on reviewing responses: Compare Jason's approval workflow with AiSDR's co-pilot setup. Use the monthly Jason price for a cancellable pilot and the annual price only when you accept the annual commitment.
You have a proven motion and want a supported rollout: Request an Artisan quote with all sender resources and human tasks itemized. Evaluate 11x when managed infrastructure is valuable enough to support its annual budget, and resolve the public pricing conflict first.
Your sellers should stay in control of outreach and conversations: Choose Amplemarket when its signals, research and sequence preparation can make those sellers more effective. Price the plan with the exact Duo features you need.
A founder can still work replies and budget is tight: Start with Apollo's relevant plan. It can reduce preparation work while preserving direct learning from buyer conversations.
The rule is simple: if you cannot fund a person to run the reply queue, evaluate a full-workflow agent with bounded human oversight. If that person already exists and their judgment is valuable, first evaluate a copilot or rep-operated platform. If there is nobody to supervise exceptions or attend meetings, fix that capacity before buying either.
When Not to Buy an AI SDR Yet
Do not buy automation before you can explain why the target should agree to talk. If the offer has not worked in direct conversations, more systematic outreach mainly creates more systematic rejection. Use a small human-led prospecting process to learn which problem, role and message fit.
A tiny target universe is another reason to wait. If each account is valuable and there are few suitable buyers, research depth and relationship ownership can matter more than throughput. A bigger contact allowance cannot expand the market you should contact.
Wait if sending domains are unhealthy, the CRM does not distinguish customer and prospect records, or no one owns opt-outs and exceptions. Those are prerequisites for a trustworthy workflow. A managed plan may help establish them, but the contract should say which work it performs and who accepts it.
Also wait if your sellers cannot attend and follow up on good meetings, or you cannot count bookings independently of a vendor dashboard. Increasing the top of the funnel will not repair either problem.
The founder's immediate alternative is modest: define one offer, review a small qualified list, handle the conversations and record what happens. Buy automation when you can name the repetitive work to remove and the person who keeps responsibility for the result.
How These Were Picked
These six were compared against vendor-owned pricing and product documentation on 2 October 2026. The criteria were documented ownership of the five SDR jobs, the public price and term, required sender/data inputs, review controls and the work a person retains.
AiSDR, Artisan Ava and 11x Alice are joined by Jason as another full-workflow candidate. Amplemarket represents the copilot approach, and Apollo is a lower-cost human-led alternative. A research-only tool or a writing-only assistant would need another stack to reach the same endpoint, so it does not receive a full-agent rank here.
No campaign trial was conducted, and no meeting-rate promise determined the ordering. Partner status did not change the scope classification. The original analysis is the dated plan verification, the identification of pricing and feature boundaries, and the explicit cost calculations above.
The Ones to Avoid
Avoid the buying mismatch, even when the underlying tool is suitable for another workflow.
- Apollo Basic as an unattended SDR: Its low price does not remove the documented human reply workflow.
- Amplemarket Startup for Duo Inbox: The needed feature is not on that plan, and draft replies still need an owner.
- Jason at the ordinary Reply sequencer price: Use the dedicated AI SDR tab and the correct billing period.
- Artisan on an unverified public dollar quote: The current vendor plan cards require a custom price.
- 11x before the annual total is resolved: The card and FAQ conflict is a procurement question to settle before signing.
Also avoid buying any of them from a meeting-rate promise alone. Without comparable targeting, spend, attribution, attendance and qualification, that percentage cannot price the meetings your company will receive.
FAQ
Do AI SDRs actually work?
The full-workflow products here document sourcing, outreach, replies and booking. Whether they work economically for your company requires a measured pilot with attributable bookings, attendance, qualification and human time included. No vendor meeting-rate claim establishes that result for your offer.
Is AI replacing SDRs?
These tools can delegate parts of the job, but replacing an accountable person is a separate decision. Keep someone responsible for targeting, claims, exceptions and meeting quality; decide on staffing only after measuring the work and results that remain.
What are the top 5 AI tools right now?
For the outbound purchase covered here, the first five are AiSDR, Jason, Ava, Alice and Amplemarket Duo, grouped by documented workflow ownership. This is not a universal ranking of AI products; Apollo is also included for buyers who want a human-led, lower-cost alternative.
What are the top 5 AI marketing tools?
This shortlist concerns outbound sales rather than all marketing work. Marketing tools for content, advertising or newsletters cannot be ranked as SDR replacements without checking whether they also source prospects, work replies and arrange meetings.
What are the big 3 AI tools?
There is no three-product standard for this SDR buying decision. Compare three workflow types instead: an agent that can own the operational chain, a copilot that prepares work for a rep, and a platform the rep operates through booking.
What is the #1 AI tool?
AiSDR Solo is the small full-workflow starting choice on this shortlist at $250 per month. That recommendation changes when you need more capacity, a different CRM tier, stronger explicit reply approvals or a seller-led workflow.
Which AI does Elon Musk use?
This comparison does not verify a public figure's personal AI use. That information would not determine which product can handle your outbound tasks, fit your budget and preserve the review controls your business needs.
Is Grok 3 really the best AI?
No general-model benchmark was performed for this comparison. A preference for a model does not establish a complete SDR workflow: you still need prospect data, sender infrastructure, reply rules, calendar routing and measured business outcomes.
Which AI is the most powerful AI?
For this purchase, maximum model capability is not the decision rule. The useful product is the one that performs the tasks you can responsibly delegate and produces qualified conversations at a cost your business can defend.
Your Next Move
Before requesting demos, write down one target segment, one offer, the human owner and the budget ceiling. Give every vendor the same requirements: the five jobs, sender resources, CRM scope, approval rules, contract term and outcome definition.
Then run a bounded pilot and count the meetings in your own records. Expand when the conversations are suitable and the full operating cost fits. If you cannot answer who will review an exception or attend a meeting, solve that first.
