AI SDR vs human SDR: which should you use?
Use both, with clear jobs. AI agents are good at research, list building and first drafts at volume. People are better at judgement, live conversations and deals with several buyers. The setup that holds up has agents do the research and drafting while reps approve what goes out, handle the replies and run the meetings.

What AI agents do well
- Research every account on a list, including the long tail beyond the top 20.
- Spot signals such as job changes, funding and new hires as they happen.
- Draft a first email grounded in one specific reason to reach out.
- Keep the CRM up to date with every touch.
What people still do better
- Judge whether a reason to reach out is strong enough to use.
- Hold a live conversation and handle objections.
- Build trust with several buyers in a larger deal.
- Notice when a message would land wrong, even if every fact in it is right.
The mix that holds up
Agents research and draft; reps approve, send and talk. Each rep reviews drafts in a few minutes instead of researching for an hour, and every email that goes out has a person behind it. Your sending domain stays healthy because volume stays at a level a person can stand behind.
How to run a fair comparison
Most comparisons don't control for anything. For a fair test, give an agent-assisted group and a rep-only group the same accounts, the same offer, the same channels and the same sending setup, then compare meetings booked and pipeline created, not emails sent.

Related questions
Will AI agents damage our email domain?
They can if they send at volume without care. Authenticate your domain (SPF, DKIM, DMARC), warm up new sending domains, keep volume sensible, and keep a person approving first touches.
Do we still need SDRs?
Yes, with a different job: fewer hours on research and list building, more time on conversations.
Should prospects know an agent drafted the email?
The email comes from the rep, who read and approved it. What matters is that every fact in it is true and a person stands behind it.
