What is an AI SDR?

A sales development rep (SDR) finds and qualifies new conversations for a sales team. An AI SDR takes over the parts that are repetitive: building a list, researching each company, writing the first email and follow-ups, sending them, sorting replies and offering times for a call.

Where products split is the line between drafting and deciding. Aries Leads, a lead generation firm, puts it this way:

We read each product’s public pages on 2 October 2026. Quotes are theirs; prices are as shown that day and can change.

Approval is common, so it is not a reason to pick one tool on its own. Ask which messages it covers (first emails, follow-ups, replies, LinkedIn), whether it can be switched off, and who in your team does it.

They save research and writing time. Whether they are worth it depends on what they produce after the reply. Two things make that hard to see.

Generic messages at volume. Aries Leads: "Full automation tends to increase generic messaging and reduce control. Agencies get better results when they automate repetitive work and keep judgment-heavy tasks human."^[9]

Counting the wrong thing. Many tools report replies or "opportunities". Instantly, for example, counts opportunities from leads "ever marked as positive, even if their status was later changed to negative", valued at an amount you set.^[10] Count calls held and clients who paid instead.

A human SDR has median on-target earnings of $80,000 ($55,000 base, $25,000 variable) in the Bridge Group’s 2025 report, before benefits, tools and a manager’s time, with around three months to ramp.^[11] A person calls, handles objections live and reads the room. Software does the research, the first drafts and the reply sorting, at any hour, and does not call.

Many teams use both: software for the work under the job, a person for judgement and calls. Sealrep vs hiring an SDR goes through when each makes sense.

1. Who approves each message, and can that be switched off by anyone on the team?
2. Whose mailboxes and domains send: yours, or ones the vendor sells you?
3. What does it do on LinkedIn, and whose account does it use?
4. What does the dashboard count as a result: a reply, a "positive" reply, a meeting held, or a payment?
5. What do the terms say about refunds and cancelling? Most tools we read say payments are not refunded.

Sealrep is an approval-first AI revenue agent: a reply can carry a payment link from your own Stripe, and a results ledger counts from first email to cash. Nothing is sent until a person approves it: one email at a time, or a whole sequence at once, with undo before each send. On LinkedIn, X and Reddit it finds and drafts, and you send. Does Sealrep send email without my approval? has the detail.

It is not a fit if you want software to send on its own at high volume: it has no setting for that today.
