12 Questions to Ask Before You Buy

Search "AI SDR tools" and you'll get dozens of near-identical listicles ranking a near-identical set of logos, most of which use the same three words to describe themselves: autonomous, verified, deliverability-safe. Almost none of them mean the same thing by those words. The category has grown fast enough that the marketing has outpaced the vocabulary — "autonomous" can mean anything from "fully self-running" to "has an autofill button," and "verified" can mean anything from "checked three layers deep" to "the email address has an @ in it."
Rather than adding another ranked list to that pile, here are the specific questions worth asking any AI SDR vendor — including us — before you sign anything. If a vendor can't give you a straight answer to most of these, that's the answer.
These sound similar and aren't. Verification-before-send stops a bad contact from ever entering a sequence. Bounce cleanup happens after the damage — your domain has already taken the reputation hit by the time a bad address gets flagged. Ask specifically which one you're getting, because "we verify emails" is technically true of both.
Shared sending infrastructure — common on lower tiers of database-style tools — means your deliverability is partly determined by every other account sharing that infrastructure, not just your own sending behavior. Sending from your own authenticated domain puts your reputation entirely in your own hands. Ask directly: is this shared, or is it mine?
A lot of "AI SDR" tools are really enrichment or research tools that expect you to plug in a separate sending platform. That's not necessarily a dealbreaker, but it changes the real cost (a second subscription) and the real complexity (two systems to keep in sync) of what you're buying. Ask plainly: does your tool send the email, or do I need another tool for that?
This is the question that separates a real autonomous system from a glorified mail-merge. A reply should pause the sequence automatically and route to a human — not get followed up on by a bot that didn't notice someone already answered. Ask to see this specific behavior, not just hear it described.
Per-seat pricing, per-credit pricing, and token-pool pricing all behave very differently at scale. Just as important: do unused credits roll over, or do they evaporate at the end of the billing cycle? A vendor that resets your balance to zero every month is quietly counting on you not using what you paid for.
Sticker price is close to meaningless on its own. A $49/month plan with a small, expensive credit allotment can cost more per usable lead than a $79/month plan with a larger one. Ask the vendor to walk through the actual cost of getting one verified, contacted lead — not the plan price.
A contact that technically matches your ICP and a contact with an actual reason to care right now are different things, and they perform completely differently. Ask what "why now" reasoning — if any — sits behind each send.
DKIM, SPF, and DMARC configured correctly, a real domain warm-up period, and sane daily sending limits are the baseline, not a bonus feature. If a vendor can't explain their warm-up process in plain terms, assume there isn't one.
Industry benchmarks put a good cold-email bounce rate under 3%, best-in-class under 1.5%. Ask the vendor what their customers typically see — a specific number, not "high accuracy." If they won't give you a number, that's informative on its own.
Some tools are genuinely autonomous out of the box. Others require someone to build and maintain workflows, sequences, or enrichment logic before anything runs. Neither is wrong, but you should know which one you're buying — "autonomous" and "configurable" get used interchangeably far too often.
Suppression lists, opt-out handling, and CAN-SPAM/GDPR-aware sending shouldn't be something you have to build yourself. Ask specifically how unsubscribes and do-not-contact lists are enforced across the whole system, not just within one campaign.
A defensible system should be able to show its work — why this contact, why now, based on what signal. A tool that can only show you an output with no reasoning behind it is a black box, and black boxes are hard to trust with your sender reputation.
For what it's worth, here's how VerifiedLead answers these: verification happens before send across deliverability, identity, and intent; sending runs on your own authenticated domain, never shared; the full pipeline — search, verify, enrich, draft, send, follow-up — runs natively without a second tool; replies pause the sequence automatically; and every contact carries the specific signal that qualified it, visible in the product, not hidden behind the output.
That's one answer to these twelve questions. It shouldn't be the only one you accept — ask them of whoever you're evaluating, including us.
