Find the email. Then proveit's real.
Give us a name and a company, or a whole domain. We resolve the real address pattern — then run it through the same 20+ checks as our verifier, so you get a verdict and a confidence score, never a hopeful guess.
A name and a company is enough.
Type who you're looking for and where they work. We test the likely address formats, corroborate against known mailboxes and public sources, and surface the one that actually resolves — with the patterns we ruled out, so you can trust the answer.
- Real pattern resolution. {first}.{last}, {f}{last} and more — tested, not assumed.
- A verdict, not a guess. Every candidate is verified by MX, SMTP and catch-all checks before you see it.
- Confidence you can read. A 0–1 score per result, plus the sources that corroborate it.
Every role mailbox at a domain, verified.
Just need to reach the right inbox at a company? Give us the domain and we'll sweep every common role address — sales@, support@, billing@, press@ — verify each one, and flag the catch-alls and dead boxes so you don't waste a send.
- One domain, every role. sales, support, info, billing, careers, press and more.
- Catch-all aware.We tell you when a domain accepts everything, so a “valid” isn't a false promise.
- Export-ready. Download the confirmed mailboxes or push them straight into your CRM.
Unknown is free. Always.
Every other finder bills you for the guess. We only charge when we resolve a mailbox and confirm it’s live — so a big slice of every run costs you nothing. Across a typical 1,000-lookup batch, this is where your credits actually go.

Find, resolve, verify — in one pass.
The finder and the verifier are the same engine. You never get an address we haven't actually checked.
Give us a name or a domain
Type a person's name + their company, or just a domain. One lookup or a whole list — the finder takes both.
We resolve the real pattern
We test the likely formats ({first}.{last}, {f}{last}…), cross-check against known mailboxes and public sources, and rule out the misses.
Then we actually verify it
Every candidate runs through the same 20+ checks — MX, SMTP, catch-all, role, disposable — so you get a verdict, not a guess.
Pay only for answers
Found and verified? One credit. Couldn't confirm a mailbox? You don't pay — and the credits you do spend never expire.
One call. Resolve and verify.
POST /v1/finder/email takes a name and a domain and returns the resolved, verified address with its score and the pattern we matched. The billed flag tells you whether a credit was charged — it never is when we can’t confirm a mailbox.

}Built for the people who actually have to reach someone.
Outbound & sales
Build a clean prospect list from names you already have — every address verified before it hits your sequencer.
Recruiting & partnerships
Reach a specific person at a company without guessing a format or burning your domain reputation on bounces.
Support & operations
Pull the right role mailbox at a vendor or partner domain, verified, so your message actually lands.
Right person. Real inbox.
We cut our bounce rate from 11.4% to 0.5% in a week. The AI explaining why each address was risky is the part our team actually loves.
The API drops straight into our signup flow. Fake and disposable emails never make it into the database anymore.
Half the price of the tool we left, and the inbox-placement testing paid for itself on the first campaign.
Good to know.
