Email Format Finder
Enter a business domain to get the dominant work-email pattern, its confidence, and how many addresses it was read from. Measured, not guessed.
Aggregate coverage and synthetic examples only. No real contacts are published here.
- You give it a domain
One business domain. No name, no login, nothing else.
kessler-systeme.de - It counts the addresses we already hold
The dominant pattern is inferred from verified addresses on that domain, with the match count and a confidence figure shown next to it. Where coverage is too thin to be reliable, the tool says so instead of publishing a pattern.
f.last@ · 78% of matches - The examples are synthetic on purpose
Sample addresses demonstrate the shape without exposing anyone. Real people, raw emails, and exports stay behind sign-in.
The pattern is right, and one of these still bounces.
A format tells you how the company builds addresses. It cannot tell you that someone left, that the mailbox was never created, or that this person is the exception. The record can: 565.8M of them, checked at export.
