10 Best AI SDR Tools of 2026
By the KeenVerdict research desk · Updated November 12, 2026 · Next review December 27, 2026 · 10 products scored

Our verdict
Pick AiSDR if you want an AI SDR that runs whole campaigns and bills only for the people it contacts. Pick Apollo.io if your reps also need a large contact database and a dialer on the same seat, and Regie.ai if a single seller wants research, drafting, a dialer and a free CRM from $41 a month. Unify and Reply.io are good middle choices, Clay and Persana AI are research and enrichment engines that feed your sequencer, and Amplemarket, Artisan and 11x fit teams ready for annual contracts and guided onboarding.
The short answer
AiSDR is the best AI SDR tool for small and midsize B2B teams in 2026 because it researches, writes and sends outreach for $1.50 per person prospected with no seat fee, as of November 2026. Apollo.io suits teams that want a contact database, sequences and AI research from $49 per seat per month billed annually, and Unify is the cheapest paid plan at $20 per seat per month. Larger teams that want a fully managed AI BDR with a sales-led rollout should look at Artisan or 11x, which quote prices on a call.
This list is for founders, SDR managers and revenue leaders who want software that finds prospects, researches them, writes personalized emails or LinkedIn messages and sends them with little manual work. We compared documented features and published prices for 10 tools and scored each on features, ease of use and value, weighted 40, 30 and 30. Prices are the cheapest paid option in US dollars as shown on each vendor's own pricing page when we checked in November 2026. Artisan and 11x do not publish prices, so theirs are marked pending.

Pay as you go at $1.50 per person prospected, charged daily; volume team plans through sales
Quoted from the AiSDR pricing page on November 12, 2026:
Pay as you go Self-serve $1.50 / person prospected
AiSDR ranks first because it is the closest match to the job of an SDR at a price a small team can test. On the self-serve plan you pay $1.50 for each person prospected, with research, list building and message writing included, charged daily and cancelable at any time. Its Ami agent builds a campaign, runs it and adjusts it as replies come in, drawing on 2B+ profiles, live signals such as job changes, new hires and funding, and waterfall enrichment across 20 data providers. Sequences mix email with LinkedIn connection requests, DMs, InMails and voice notes, and a unified inbox classifies replies and answers them in 5 to 10 minutes or waits for approval in co-pilot mode. Deliverability tools include triple bounce checks, lookalike domains and warmup. Teams contacting more than 1,000 people a month can move to a team plan with up to 40% lower cost per contact, Salesforce sync and visitor tracking, on quarterly contracts.
What works
- +Self-serve start without a sales call, charged daily and stoppable anytime
- +Research, lists and writing cost nothing beyond the per-person fee
- +Triple bounce checks, lookalike domains and continuous warmup
What does not
- −Salesforce integration and website visitor tracking are on team plans only
- −A warmed-up mailbox costs $33 extra if you lack a sales mailbox
- −Team plans need quarterly contracts
- Price

Free plan; Basic $49 per seat per month billed annually, Professional $79
Quoted from the Apollo.io pricing page on November 12, 2026:
$49 Per seat per month, billed annually
Apollo.io is the runner-up because it gives reps an AI research and writing layer on top of a large contact database for less than most dedicated AI SDR products. The free plan includes 900 credits per seat per year and a limited AI Assistant, and Basic at $49 per seat per month billed annually adds 30,000 credits, email sequencing and core integrations. Professional at $79 is the plan Apollo recommends for full-time reps who need higher credit limits, AI features, call recording and advanced CRM integrations. Credits pay for emails, phone numbers, warmup, mailboxes and AI-researched data, and they are pooled across the team. The trade-off is that Apollo is a toolkit for reps rather than an autonomous agent: a person still builds the sequence and decides who to contact. All seats must sit on the same plan, so mixed teams pay for the highest need. Apollo says over 600,000 companies use it.
What works
- +Free plan with 900 credits per seat per year
- +Basic includes 30,000 credits per seat per year, granted upfront
- +One seat covers data, outreach and deal management
What does not
- −AI features in full, call recording and higher credit limits need Professional at $79
- −Every seat on an account must be on the same plan
- −The Organization plan needs at least 3 seats at $119 each

Free plan with 250 credits per person; Pro $41 per month billed annually or $49 monthly; Team $125 per seat billed annually
Quoted from the Regie.ai pricing page on November 12, 2026:
Pro, for one person, is $41 a month billed annually or $49 billed monthly.
Regie.ai sells its prospecting product as RegieGO, and it ranks third because it gives one seller research, drafting, enrichment and a dialer for $41 a month billed annually, or $49 monthly. The free plan is real: 250 one-time credits per person for up to 10 people, with no credit card. Every plan includes a free built-in CRM, so a small team does not need to buy one, and teams on HubSpot or Salesforce can connect them and switch on write-back. Email goes from your own Gmail or Outlook, each contact is verified before sending, and sending is throttled with unsubscribes handled. Pro adds 5,000 credits a month and a parallel dialer with local numbers, and enrichment that comes up empty does not use credits. The limits are on the team side: Team costs $125 per seat billed annually with a two-seat minimum, extra credits cannot be bought separately, and custom CRM sync sits on Enterprise.
What works
- +Free plan with 250 one-time credits per person for up to 10 people, no card required
- +Enrichment that finds nothing costs no credits
- +Overage billing can be capped by the workspace owner
What does not
- −Team plan needs at least 2 seats at $125 each billed annually
- −Extra credits cannot be bought on their own
- −Custom CRM sync and SOC 2 security are on Enterprise
- Free plan

Free plan; Base $20 per seat per month billed monthly, Pro $60 per seat
Quoted from the Unify pricing page on November 12, 2026:
$20 / seat / mo Billed monthly 800 credits / seat / mo
Unify is the cheapest way on this list to put AI copywriting and signal-based prospecting in a rep's hands. The free plan covers up to 3 seats with limited credits, and Base costs $20 per seat per month billed monthly with 800 credits, AI email copywriting, phone and email enrichment and job change and hiring signals. Its data covers 1.1B+ people and 65M+ companies from 40+ data sources, and signals extend to funding, tech stack, news, paid ad activity and warm intro paths. Pro at $60 per seat adds 2,400 credits, Slack notifications and read-only HubSpot and Salesforce sync, with a 14-day trial that needs no card. The gaps show for larger teams: read-write CRM sync, website intent, signal-triggered automations, managed mailboxes with warmup and the power dialer are all on the custom-priced Business plan, billed annually. For an individual rep or a small team, though, the entry price is hard to beat.
What works
- +Cheapest paid seat here at $20 per month, billed monthly
- +Free plan for up to 3 seats
- +Pro trial runs 14 days with no credit card
What does not
- −HubSpot and Salesforce sync is read-only below the Business plan
- −Managed mailboxes, warmup and rotation are Business only
- −The Free plan's credits are limited

Startup plan $600 per month on an annual term with 2 users included; Growth and Elite custom
Quoted from the Amplemarket pricing page on November 12, 2026:
$600/mo annual term 2 users included
Amplemarket scores well on features because its Duo AI layer covers most of the SDR workflow on top of its own B2B database. Duo Copilot and Duo Copywriter write personalized emails, Duo Signals flags buying intent, AI agents find buyers and research prospects, and an MCP add-on lets reps prospect and research from Claude or ChatGPT. The Startup plan costs $600 a month on an annual term and includes 2 users, 27,000 contacts, multichannel sequences, AI intent signals and Duo Copilot, plus scaled CSM support and community onboarding. Growth and Elite are custom priced, with 4 and 10 users, 140,000 and 400,000 contacts, and Duo Voice for AI voice messages; Duo Inbox, which drafts replies to every prospect email, is listed on Elite. The value score is lower because the entry price and annual commitment are high for a small team, though Amplemarket can replace a separate database and sequencer.
What works
- +Startup plan includes 27,000 contacts and 2 users
- +All plans include a free trial
- +Data, signals and sequences in one subscription
What does not

Free plan; Launch $167 per month at the annual rate, Growth $446
Quoted from the Clay pricing page on November 12, 2026:
For small teams building and automating prospecting workflows $167/mo
Clay has the deepest research toolkit here, which is why it leads on features and trails on ease of use. It is a spreadsheet-style workspace where you pull prospects, run multi-provider enrichment waterfalls and ask Claygent, its AI web research agent, for any custom data point, then send the result through Clay's own email sequencer or a sequencing integration. The free plan includes 500 actions and 100 data credits a month with unlimited seats, tables of up to 200 rows and Claygent. Launch costs $167 a month at the annual rate, starts at 15,000 actions a month and adds phone enrichment, unlimited Audience search and signals for job changes, promotions, new hires and company news. Growth at $446 adds CRM auto-sync, any HTTP API, web intent signals and domain and mailbox buying for the sequencer. Clay rewards teams with someone who enjoys building workflows; teams that want the AI to run campaigns alone will set up faster with AiSDR or Artisan.
What works
- +Free plan with 500 actions a month and unlimited seats
- +Bring your own API key for AI models
- +Actions and data credits can be expanded at any time
What does not
- −Building tables and waterfalls takes more setup than an autonomous AI SDR
- −Free plan tables run up to 200 rows
- −CRM auto-sync needs Growth at $446 a month
- Free plan

US price check pending. See the Artisan pricing page.
Artisan's Ava is one of the most complete autonomous AI BDRs we compared: she finds leads from 250M+ verified B2B contacts, runs email and social campaigns, handles replies and books meetings, and sends in your reps' names from your own domains. Controls are good, with approve-before-send, locked tone and calls to action, banned phrases and writing coaching. Salesforce and HubSpot sync both ways, custom webhooks bring in your own data and an AI dialer can be added per seat, with a brief before each call and a follow-up after. Every plan includes CSM support in a shared Slack channel and onboarding; Scale adds a dedicated CSM and Enterprise a forward-deployed strategist. Artisan is SOC 2 Type II certified. The reason it ranks ninth is value transparency: there are no public prices, the Team plan is sized at about 2,500 leads contacted a month and Scale at about 6,000, and you need a sales call to learn the cost.
What works
- +Ava sends in your reps' names from your own domains
- +CSM support and onboarding in a shared Slack channel on every plan
- +SOC 2 Type II certified with SSO and SAML
What does not
- −No published prices; every plan goes through sales

Price
Free plan; Starter $68 per month billed annually or $85 monthly
Quoted from the Persana AI pricing page on November 12, 2026:
Starter Best for individuals $68 /mo Billed annually 24k credits/yr
Persana AI is a research and enrichment tool first, which makes it a good feeder for AI-written outreach rather than a full replacement for an SDR. Its Quantum AI Research Agent, web scrapers and waterfall enrichment across 100+ data providers build the prospect profile, and the plan comparison also lists Persana AI Agents, Autopilot AI Agents and a full-service AI SDR. Every plan allows unlimited users. The free plan gives 50 credits with no billing, and Starter costs $68 a month billed annually or $85 monthly for 24,000 credits a year, with credit rollover and searches of up to 7,000 people or companies. One email found costs 1 credit and one phone number 10 credits, so phone-heavy teams burn credits fast. Growth at $151 and Pro at $400 a month, both billed annually, raise credits to 60,000 and 216,000 a year. Ease of use scores lower than the autonomous tools because you assemble the workflow yourself.
What works
- +Unlimited users on every plan
- +Credit rollover on paid plans
- +Free plan with 50 credits and no billing
What does not
- −Phone numbers cost 10 credits each
- −Starter caps searches at 7,000 people or companies per search

US price check pending. See the 11x pricing page.
11x is the broadest platform here, built for revenue teams that want AI agents on every stage rather than outbound email alone. Its outbound agents act on live signals for target accounts, run deep research on each prospect by combining account updates, contact information and CRM context, and coordinate email, social and dials in one sequence with deliverability managed in house. It can also re-engage inactive and closed-lost leads and de-anonymize website visitors. On the inbound side, voice and chat agents respond to new leads in under 60 seconds, qualify them in several languages and book meetings with the right rep, and expansion agents look for upsell and cross-sell openings in the customer base. The feature score reflects that range. It finishes last because 11x publishes no prices, its pricing page did not load when we checked, and every deal starts with a demo, which makes it hard for smaller teams to compare cost.
What works
- +Covers inbound, outbound and expansion on one platform
- +Two-way conversations on voice, chat, email, SMS and WhatsApp
- +Real-time contact data built in
What does not
- −No published pricing; you book a demo to get a quote
- −Broad platform is more than a small team needs for outbound email alone
- −Setup runs through the 11x team rather than self-serve signup
- Channels
- Voice, chat, email, social, SMS, WhatsApp, human dialer

Before you choose
Decide how much the AI should do on its own
Some tools run outbound end to end: AiSDR, Artisan's Ava, 11x and Reply.io's Jason AI SDR find leads, write messages, send them and answer replies. Others, such as Clay, Persana AI and Unify, research and draft while a person keeps control of the sequence. Most autonomous tools still offer a review step: Artisan lets you approve before sending and AiSDR has a co-pilot mode.
Understand the pricing model before you compare numbers
AI SDR pricing comes in three shapes. AiSDR charges $1.50 per person prospected. Apollo.io, Unify and Regie.ai charge per seat and meter work with credits. Clay and Persana AI sell pools of actions or credits. Amplemarket starts at $600 a month on an annual term with 2 users included, and Artisan and 11x quote a price after a demo.
Check where the contact data comes from
Personalized outreach is only as good as the records behind it. Unify lists 1.1B+ people and 65M+ companies from 40+ data sources, AiSDR uses waterfall enrichment across 20 data providers, Persana AI lists 100+ data providers and Artisan includes 250M+ verified B2B contacts. Clay lets you chain several providers in one waterfall.
Protect your sending domains
AI tools send a lot of email, so look at mailbox and deliverability features. AiSDR sells a warmed-up mailbox for $33 and runs triple bounce checks, Unify's Business plan includes managed Gmail and Outlook mailboxes with warmup and rotation, and Regie.ai sends from your own Gmail or Outlook and verifies every contact before sending.
Questions readers ask
- What is the best AI SDR tool?
- AiSDR is the best AI SDR tool for most small and midsize B2B teams in 2026. It researches prospects, writes and sends email and LinkedIn outreach and handles replies for $1.50 per person prospected, with no seat fee, as of November 2026.
- What is an AI SDR?
- An AI SDR is software that does the work of a sales development rep: it finds prospects, researches them, writes personalized messages, sends them and answers replies. Examples include AiSDR, Artisan's Ava, 11x and Reply.io's Jason AI SDR.
- How much does an AI SDR cost?
- Published prices run from $20 per seat a month to $600 a month and up as of November 2026. Unify Base costs $20 per seat billed monthly, AiSDR charges $1.50 per person prospected, Reply.io's Jason AI SDR starts at $500 a month and Amplemarket starts at $600 a month on an annual term; Artisan and 11x quote prices after a demo.

- Can an AI SDR replace a human SDR?
- It can take over the repetitive parts, but vendors still position humans for live conversations and closing. Artisan says Ava handles finding leads, writing outreach and replies so reps spend time on live conversations, and 11x routes qualified leads to human reps.
- Which AI SDR works with Salesforce?
- Artisan, Regie.ai, Unify and AiSDR all document Salesforce connections, with limits by plan. Artisan syncs Salesforce both ways, Unify's sync is read-only below Business, and AiSDR includes Salesforce on its team plans.
- What is the difference between Clay and an AI SDR?
- Clay is a research and enrichment workspace, while an AI SDR runs the whole outreach process. Clay's Claygent agent researches custom data points and can send through Clay's sequencer, but you design the workflow; AiSDR or Artisan run campaigns and replies for you.
