Know exactly what's in your list.
Every address checked individually. You only pay when we return a confirmed result — deliverable or bounce. Everything uncertain costs nothing.
From $10/mo · 24,000 confirmed results
Result types
Five results. Two of them cost credits.
Every address in your list comes back with one of these. The two you can act on are the only two you pay for.
The mailbox exists and will accept email. Your list, cleaned.
The mailbox does not exist. Worth knowing before it damages your sender reputation.
The domain accepts any address sent to it, including invented ones. We flag it at no cost. Resolving which specific addresses are real is a separate step.
Learn about catch-all resolutionThe server did not give a clear enough response for a definitive answer. You are not charged for ambiguity.
Signs of greylisting or rate limiting on the server. Flagged rather than guessed. Never charged.
Always free, regardless of result:
info@, support@, noreply@ and similar team inboxes never reach a real person. Flagged automatically, never charged.
Temporary email providers identified and flagged in your results.
Any address you have checked in the last 180 days costs nothing to re-verify.
Bulk upload
Upload your list. Get back one that means something.
Upload a CSV or spreadsheet. Every address is checked individually and comes back labelled. Confirmed deliverable, confirmed bounce, catch-all flagged, uncertain flagged — every result is specific.
You pay for the confirmed results. Everything else is free.
When the job completes you can filter by result type before downloading. Confirmed deliverables only. Bounces only. Catch-all addresses set aside for resolution. You choose what to do with each group.
You upload 10,000 emails.

Result cache
Already checked this address? Free for 180 days.
Results are cached per account. Re-uploading a list that includes previously verified addresses costs nothing for those addresses — only new ones draw credits.
You can always re-check any address at any time — if the cached result is still within 180 days, it costs nothing. If you want a fresh verification, that's a new check at standard cost.
Your cache is private. Results are not shared across accounts. Cache entries are deleted automatically after 180 days.
What comes next
Some of your addresses will come back as catch-all.
Catch-all domains accept every address you send — real or invented. Standard verification flags the domain and cannot go further. If you need to know which individual addresses on those domains are actually real, that requires catch-all resolution.
