Best AI SDR software in 2026

1AiSDR, best for pay as you go outbound

AiSDR is the one full AI SDR here you can start without a sales call or a contract. The self-serve plan costs $1.50 per person prospected, is charged daily and stops when you stop. Research, list building and writing are included in that price.

Its agent, Ami, builds the campaign and runs it. Prospects come from a pool of 2B+ profiles with live signals such as job changes and funding, and one sequence can mix email with LinkedIn connection requests, DMs, InMails and voice notes. Replies from both channels land in one inbox, where AI sorts and answers them, either within about 5 to 10 minutes or in a co-pilot mode where you approve first.

The catch is the CRM. HubSpot syncs both ways on every plan, but Salesforce sits on the Team plans, which are for 1,000+ contacts a month and come with quarterly contracts.

2Artisan, best for a managed AI BDR

Artisan sells Ava, which it calls an AI BDR. Ava finds and enriches leads from 250M+ contacts and 22+ data sources, sends multi-channel outreach across email and social, handles every reply and books meetings on your reps' calendars. Emails go out in your reps' names from your own domains.

You choose how much rope Ava gets. Approval mode holds every draft for a click, tone and banned phrases can be locked, and escalation rules decide when a human takes over. Salesforce and HubSpot sync both ways on every plan.

Pricing is the hard part. The tiers are sized by leads contacted (about 2,500 a month on Team, about 6,000 on Scale), but every tier says "Talk to sales." Plan on a demo before you see a number.

311x, best for enterprise outbound

11x runs two agents. Alice handles outbound: she builds lists from live signals and a 400M-contact database, researches each buyer, writes the message and runs it across email, social and a power dialer. Julian handles inbound with voice and chat agents that qualify leads and book meetings.

On the reply side, Smart Replies read each answer, respond to questions and common objections, and pass sensitive threads to your team. Every activity syncs back to the CRM.

There is no pricing page at all, and every button asks you to book a demo. That puts 11x out of reach for anyone who wants to test with a card.

4Reply.io (Jason AI), best for teams already on Reply

Jason is the AI SDR inside Reply.io, priced from $500 a month. Reply says Jason finds prospects, writes personalized messages, manages the responses and books meetings, across email and LinkedIn and in 50+ languages. An approval mode lets you check messages before they send.

If you'd rather keep the work manual, Reply's sequencer starts at $49 per user a month on annual billing, and LinkedIn automation is a $69 add-on per account. Reply also syncs with Salesforce, HubSpot, Pipedrive, Copper and Close. Teams leaving Reply for a cheaper sender can compare options in our best cold email software roundup.

5Salesforge (Agent Frank), best for per-contact pricing

Agent Frank is Salesforge's AI SDR. He searches a 500M+ contact engine, writes the emails, follows up and books the meeting, with auto-pilot and co-pilot modes and support for 20+ languages. Salesforge includes unlimited email and LinkedIn senders, so you don't pay per seat.

You pay for active contacts, meaning the prospects Frank is working at any one time. Tier 1 is $499 a month on annual billing for 1,000 active contacts, and past 2,000 a month the rate is $0.25 per contact. A dedicated account manager and a shared Slack channel come with it.

New mailboxes need about two weeks of warmup before Frank sends, so the first month starts slow.

6Amplemarket, best for reps who want a copilot

Amplemarket leans toward helping reps rather than replacing them. Duo, its AI copilot, writes the emails and surfaces intent signals, and the platform adds a B2B database, multichannel sequences, email validation and a dialer. Duo Inbox, which drafts a reply to every prospect email, only comes on Elite.

Startup costs $600 a month on an annual term with 2 users and 27,000 contacts. Growth and Elite are custom-priced, with 4 and 10 users. Every plan has a free trial.

7Clay, best for building your own AI SDR

Clay is a toolkit, not a finished agent. You pull data from 150+ providers, run Claygent (its web-research AI agent) to find custom details on each lead, and send through the Clay Sequencer or a sequencer you already use. Growth adds CRM auto-sync and lets you buy domains and mailboxes inside Clay.

What it doesn't list is the back half of the SDR job: answering replies and booking meetings. If you build on Clay, plan for a sender and a way to work the replies.

The Free plan gives 6,000 actions a year. Launch is listed at $167 a month and Growth at $446, with 10% off on annual billing and a 14-day trial.

8Regie.ai, best for reps who prospect and dial

RegieGO, from Regie.ai, puts research, enrichment, drafting, agents and a power dialer in one workspace, with a free built-in CRM or a connection to HubSpot, Salesforce or Monday CRM. Emails go out from your own Gmail or Outlook. It runs on credits, and enrichment that finds nothing costs nothing.

Free gives each person 250 one-time credits with no card. Pro is $49 a month ($41 on annual) for 5,000 credits, and Team is $150 per seat a month with a two-seat minimum. The pricing page doesn't list automatic reply handling or meeting booking, so treat it as a rep's assistant rather than a stand-in for one.

9Qualified (Piper), best for inbound website leads

Piper works the other side of the funnel. Instead of cold outbound, she talks to visitors on your website by text, voice or video, follows up by email and books meetings. Qualified connects to Salesforce CRM and 20+ other go-to-market systems.

Plans are sized by web sessions and email contacts (Premier covers 250K monthly web sessions and 2.5K monthly active email contacts), and all three tiers are "Contact us." Pick Piper if inbound demand goes unworked. For cold outbound, look higher up this list.

Do you need a full AI SDR or just AI on the replies?

Most AI SDR software bundles five jobs, and you pay for all of them. Plenty of agencies and outbound teams already have the first three covered: a list provider, copy they trust and a sequencer such as Instantly or Smartlead (our Instantly vs Apollo breakdown shows how a list tool and a sender split that work). What slips is the back half. Interested replies sit unanswered, out-of-office notes get ignored, and referrals to "talk to my colleague" never get a follow-up.

Revbound is not an AI SDR, which is why it isn't ranked above. It doesn't find prospects or send the first email. It pulls every reply from Instantly, Smartlead, Email Bison, PlusVibe, SendKit and ArcSend into one inbox, sorts each one with AI (interested, meeting requested, out of office, referral, not interested), drafts or sends the answer, offers times that are free on your Cal.com or Google Calendar and books the meeting when the lead says yes.

The follow-ups run without you: it writes back when an out-of-office lead returns, contacts the person a lead refers you to, and keeps following up for about two months (our cold email follow up guide covers the timing behind that). If your sequence itself needs work first, start with how to build a cold email sequence.

Plans are Solo $49, Agency $99 and Connector $149 a month for unlimited clients, month to month with AI included; Agency and up add client workspaces, client reports and meeting proof. See Revbound pricing, or the Master Inbox alternative comparison if you're weighing reply inboxes.
