Work emails that
actually deliver
Give us a name and a company domain. We work out the company’s email convention, then check the address against their mail server before handing it to you — so your cold outreach doesn’t bounce and your sender reputation survives.
- Verified against the mail server
- You pay only for usable results
- Catch-alls flagged, never faked
- Bulk CSV and a clean JSON API
Real lookup against the live mail server — not a sample.
Guessing is cheap. Confirming is the hard part.
Anyone can assemble first.last@company.com. The work is proving a human actually reads it — and admitting when nobody does.
Reuse what we know
If the company's email convention has been established before, it is applied instantly — no lookup cost, no waiting.
Rank the candidates
Thirteen naming conventions are ordered by what the evidence says is most likely for that specific domain.
Ask the mail server
Candidates are checked one at a time until a mailbox is accepted. Catch-all domains are detected and flagged, never faked.
Learn from the hit
A confirmed address teaches us the company's pattern, so the next person there is usually right on the first try.
One credit, one usable email
You are charged when a lookup returns something you can act on, and not otherwise. A miss costs nothing, and looking up someone you have already found costs nothing.
Credits never expire — they roll over for as long as you keep them, including if you downgrade or cancel. Every one is itemised in a ledger you can read.
| Outcome | Cost |
|---|---|
Verified The mail server accepted the mailbox | 1 credit |
Catch-all Domain accepts everything — flagged, not disguised as verified | 1 credit |
Not found Every candidate was rejected | Free |
Repeat lookup Someone you have already found | Free |
Buy credits, spend them on hits
One credit is one usable email, and credits never expire. Verification, catch-all detection and bulk processing are included at every tier — larger plans simply cost less per credit.

}Questions
How is this different from a pattern guesser?
Most cheap finders return first.last@company.com and call it a result. Every address here is checked against the receiving mail server before it is returned, and anything unconfirmed is labelled as such rather than dressed up as verified.
What happens with catch-all domains?
Some companies accept mail to any address, so no tool on earth can confirm a specific mailbox there. We detect it, return the best pattern match, and mark it catch-all — you decide whether to send.
Do credits expire?
No. Credits sit in your wallet until you spend them, with a full ledger of what each one went to.
Can I use it from my own tools?
Yes. Everything the web app does is available over a JSON API with a bearer key, so it drops into Clay, n8n, Make, or your own code.
Try it on someone you actually need
3 free lookups a day, no card and no account. If the address comes back verified, it is genuinely verified.
