What can an AI SDR reliably do today?

Research and enrich records, draft a first touch, classify replies into a few buckets, and book meetings against calendar rules. These have testable pass conditions, which is why they hold up.

What should an AI SDR never do?

Negotiate price, handle an unusual objection, or make any commitment on your behalf. Those need a person who can be held to the answer, and a wrong answer is expensive and hard to detect.

How do you test a vendor's AI SDR claims?

On your own data, not their demo. Label a few hundred real replies, run the classifier, and measure accuracy per bucket. Vendor benchmarks are directional at best and rarely match your vocabulary.

Does the AI SDR reply without a human first?

Not at the start. Drafts go through a review gate until measured accuracy justifies removing it. Teams that skip that step discover the error rate through customers, which is the expensive way.

Will this reduce our SDR headcount?

That is your decision, not an outcome we promise. What changes is the mix: less research and triage, more conversations that needed a person. Whether that means fewer people depends on your pipeline.

AI SDR Setup

An AI SDR automates research, first-touch drafting, reply classification, and meeting booking. It does not handle pricing negotiation, unusual objections, or anything requiring a commitment. OperStack sets the boundary per task and tests each one on your own data before it goes live. Most engagements take 3 to 6 weeks including the evaluation period.

The task split is the whole engagement

“AI SDR” names a bundle, and bundles hide the important question: which task, under which conditions. Research is close to solved. Reply classification works well on common intents and degrades on ambiguous ones. Objection handling is not close.

We take your actual SDR workflow, list the steps, and mark each one automated, assisted, or human. The list is short and boring and it is what makes the rest work.

The task by task breakdown is in AI SDR versus human SDR.

Test on your data, not their demo

Every vendor demo works. It works because the examples were chosen. Your inbox contains replies in your customers’ vocabulary, with your product names and your edge cases.

The only test that predicts production is a labelled set from your own inbox, scored per bucket. Expect the accuracy on “not now” versus “interested” to be materially worse than on “unsubscribe”, and plan the escalation around that gap.

Confidence is a routing input, not a score to admire

A classification with 62 percent confidence should not be treated the same as one with 95. Below the threshold the record goes to a human with the draft attached, and that is a success condition, not a failure.

How to separate fit from intent and where the handoff sits is covered in AI lead qualification.

The limit worth stating plainly

If your reps are slow to reply because they are busy, an AI SDR helps. If they are slow because nobody owns the queue overnight, the fix is a routing rule and a fallback owner, which is cheaper and more reliable than a model.

The speed-to-lead guide covers how to tell those two apart before you buy anything.

What the engagement covers

Task split: which SDR steps are automated, which are assisted, which stay fully human
Research and enrichment before first touch, with sources logged per record
First-touch drafting with a review gate until accuracy is measured, not assumed
Reply classification into interested, not now, wrong person, and unsubscribe
Meeting booking with calendar rules and a fallback when no slot fits
Escalation: what reaches a human immediately, and how fast

What you keep

A written task boundary, so nobody has to guess what the bot is allowed to say
A labelled evaluation set from your own inbox, with measured accuracy per task
Escalation rules and a kill switch with a named owner

What this does not cover

Cold outbound list buying or scraping. We work on inbound and existing lists you own
Autonomous pricing or discount decisions. That stays human, without exception
Replacing your SDR team. The task split usually redistributes work rather than removing it

If one of these is the actual problem, say so on the audit call and we will point you somewhere better rather than sell you the wrong module.
