The Email Finder Service That
Verifies Before You Send.

An email finder service takes the details you already have, a name, a company, or just a domain, and returns the matching work email address. Verifox adds the step most finders skip: every address is verified at the mail server before you see it, so the output is a sendable contact, not a guess. You can try the self-serve email finder tool right now, no account needed to start.

In three stages. The finder first generates the address patterns the target domain is likely to use, the firstname.lastname and f.lastname variants you see in the wild. It then cross-references the candidates against public sources so the company's real format rises to the top. Finally, the best candidate is confirmed with a live SMTP handshake and mailbox ping through the email verification engine, and the result lands with a confidence score attached.

Accurate enough to send to, because nothing unverified leaves the pipeline. The verification engine behind every result measured 99.99% accuracy on a 1,000-address benchmark list, and each found address carries a 0 to 100 confidence score so you can set your own bar. Addresses that fail verification are filtered out rather than padded into your export to inflate the count.

Search by domain when you know the company but not the people: a domain search maps every address we can identify there, the fastest way into a new account. Search by name when you know exactly who you want: a name-based email lookup tests the likely patterns for that one person and returns the strongest verified match with its confidence score.

It is the engine's 0 to 100 estimate that the address will accept your mail. High scores are mailboxes confirmed at the SMTP level. Mid-range scores usually mean a catch-all domain, where the server claims to accept everything; that is where the AI-confidence layer earns its keep, since 20-40% of B2B addresses sit behind catch-alls. Low scores mean we could not confirm the mailbox, so you decide whether the send is worth the bounce risk.

Yes. Upload a CSV of names and companies, or a list of domains, and the bulk email finder returns the file with addresses, confidence scores, and verification verdicts filled in. The verification layer processes about 10,000 emails a minute on the standard tier, so even a large prospect list comes back the same morning, ready for your sequencer.

Finding a business contact for legitimate B2B outreach is permitted under GDPR's legitimate-interest basis, provided you honor opt-outs and follow CAN-SPAM. Verifox works only from the inputs you give it plus public sources; we never scrape platforms or resell contact databases. Submitted data is processed in memory, never stored, logged, or sold, and the service is SOC 2 Type II audited. The full stance is in the privacy policy.

A finder discovers an address you do not have; a verifier confirms an address you do. Verifox welds the two together: discovery runs first, then the 9-point email verification service inspects the result before delivery. If you already hold an address and just want a verdict, the free email checker gives you 4 verifications a day with no account at all.

Both. The REST API exposes find-and-verify endpoints that return the address, the confidence score, and the verification verdict as JSON, so the finder slots into a CRM, a sequencer, or your own pipeline. For AI agents there is a native MCP server: point Claude, Cursor, or a custom agent at it and the find and verify tools are wired without glue code.

Starting costs nothing: sign up and you get 1,000 free credits, or 2,500 if you register with a work email, no card required. After that, credits are pay as you go and never expire, so an unused pack in March is still good in December. Volume rates are geo-localized, so the pricing page shows the numbers for your region.
