# Pick an AI SDR that books real meetings

An AI SDR promises to do the outbound grind a human rep does: find accounts, research them, write the message, send across channels and book the meeting. The category splits by how much control you hand over. Some run the whole play autonomously, some fire off a signal you defined, and some sit beside a human and speed the parts a rep hates. Judge every one on meetings held and pipeline, not emails sent.

## Hand the whole play to the agent

Fully-managed AI SDRs own the sequence end to end: sourcing, research, copy, sending and reply handling. They save the most time and give you the least control, so the risk is deliverability and off-brand messages at volume. Trial on a narrow segment and read every draft before it sends.

## Turn a buying signal into outbound

Signal-driven agents wait for an event you care about (a job change, a funding round, a product signal) and build the list, research and campaign off it. They target intent instead of blasting a static list, so the spend follows real timing. Watch how the signal source is priced and how fresh it stays.

## Keep a human in the loop

Copilots and SDR workspaces speed the parts a rep hates (research, first drafts, follow-up) while a person still owns the send. You keep brand control and the tool earns its cost by lifting rep output, not replacing the rep. Measure it on reply rate and meetings, not activity.

**What is the difference between an AI SDR and a sales engagement tool?**

A sales engagement tool sends and tracks sequences a human wrote. An AI SDR decides who to contact, researches them, writes the message and often handles replies. The line blurs as engagement tools add agents, so compare on how much of the play runs without a person and how much control you keep.

**How should I trial an AI SDR?**

Run it on one narrow, well-understood segment for a full sales cycle and read every message before it sends. Count meetings held and qualified pipeline, not emails sent or opens. Ask each vendor for the full cost including sending infrastructure, data and any managed-service fee.

**Do AI SDRs hurt email deliverability?**

They can, because volume plus generic copy is exactly what spam filters and recipients punish. The tools that survive pair warmup, inbox rotation and tight targeting with a human check on the message. Test with your own domain reputation in mind and start small.
