How the email finder works

From a name and a company domain to a verified address: the pattern search, the live verification, and the 20-or-1 pricing.

Give the finder a person's name and their company domain. It generates the address patterns companies actually use (first.last, flast, first, …) and verifies each candidate live, returning only an address that actually exists: no guesses, no "confidence scores" on unverified strings.

What it costs

20 credits when we find a verified address, 1 credit when we don't. You are never charged 20 for a guess. In bulk finder jobs the worst case is held up front and the difference refunded per row when the job settles.

When nothing is found

Three honest outcomes: not found (no pattern resolved to a real mailbox), catch-all (the domain accepts everything, so no specific mailbox can be confirmed; why that matters), and unresolvable (the domain cannot receive mail at all).

Getting better hit rates

A last name unlocks many more patterns and materially improves the hit rate. Use the bare domain (acme.com), not a full URL.
