The AI SDR category exploded because the math is brutal: a US SDR costs somewhere around $85,000 to $100,000 a year fully loaded (our assumption, not a survey), and the tools below promise the top of that job for a fraction. Some deliver, some are demos wearing a pricing page. We ranked all 9 by autonomy, data quality and real cost, with prices checked on each vendor's own page in September 2026.
What an AI SDR actually does
Strip the marketing and the job splits into five tasks:
- Sourcing: pull prospects matching your ICP from a database or your own list.
- Research: read the prospect's company and role for context.
- Writing: produce a personalized first email and the follow-ups.
- Sending: deliver at safe volumes across warmed mailboxes.
- Reply handling: classify responses, draft answers and put your booking link in front of the interested ones.
Autonomous agents claim all five. Copilots do two or three and leave sending or replies to you. Before you buy, check whether "books meetings" means writing to your calendar or sending a link.

When AI SDRs work (and when they fail)
They work when:
- Your ICP is broad enough that volume matters (1,000+ target accounts).
- Your offer is simple to explain in two sentences.
- You have infrastructure: warmed domains, verified lists, authentication.
They fail when:
- The tool ships with unverified data and your bounce rate torches the domain in week one.
- Your sale needs deep personalization for a 50-account named list.
- You expected zero supervision. Every agent still needs weekly steering.
The pattern in every failed rollout we see: teams bought the agent but skipped the boring parts, warm-up and verification. AI scales whatever foundation you give it, including a broken one.
Tool vs full-stack approach
Most agents sell the writing and sending, then leave data and mailboxes to other vendors. Getlead's AI SDR sits on the whole stack: a 177M+ contact database, SMTP verification, 36 pre-warmed mailboxes, follow-ups, reply classification and drafted answers in one inbox.
- It writes one email per lead, sends, follows up and labels every reply.
- Opt-outs are suppressed automatically.
- It puts your booking link in replies; it does not book into your calendar.
- $697 a month, billed monthly, cancel anytime. Start with 1,000 free leads.
The honest trade-off: an enterprise agent comes with onboarding and a success manager on an annual contract. If you want a published price and to start today, the stack is the faster route.
FAQ
What is an AI SDR tool?
An AI SDR tool automates the work of a sales development rep: finding prospects, researching them, writing personalized outreach, sending sequences and sorting the replies. Full agents aim to run the whole top of the funnel; copilot tools make a human SDR faster.
How much do AI SDR tools cost?
Prices checked September 2026: Regie.ai starts at $49 a month (Team is $150 per seat). AiSDR runs $250 to $2,500 a month. Jason AI by Reply.io is $500 to $1,000 a month billed annually. 11x Growth is $3,750 a month, billed annually only, which is $45,000 a year. Artisan publishes no price; third-party estimates put it at $2,000 to $10,000+ a month. Getlead is $697 a month with unlimited leads and 36 pre-warmed mailboxes included.
Can an AI SDR fully replace a human SDR?
For top-of-funnel volume work (list building, first touches, follow-ups, reply sorting), largely yes. For discovery calls and complex objection handling, no. The teams getting the best results use AI for volume and humans for the conversations that follow.
Do AI SDR tools book meetings?
Check what a tool actually does before you assume it writes to your calendar. Getlead's AI SDR drafts the answer to an interested reply with your booking link in it, and the prospect picks a time on your own scheduling page. It does not book into your calendar.
Do AI SDR tools hurt deliverability?
The AI does not hurt deliverability; bad infrastructure does. Whatever tool you pick, you still need warmed domains, SPF, DKIM, DMARC and verified lists. AI-written volume on cold infrastructure burns domains faster because it scales the mistake.
What is the cheapest AI SDR tool?
The lowest published price is Regie.ai Pro at $49 a month, a credit-based copilot. The cheapest self-serve agent is AiSDR Solo at $250 a month for 200 contacts. If you need the data and mailboxes as well, Getlead bundles leads, verification, 36 warm mailboxes and the AI SDR for $697 a month.
