Email Permutation
Generating likely email formats from a name and domain, then verifying which one actually exists.
Definition
Email permutation is a technique email finders use to guess an address by combining a person's name with their company domain in common patterns (first.last@, flast@, first@) and then verifying each candidate to find the one that's real. It works because most companies use a consistent format. Verification is essential, since unverified permutations are just guesses that risk bounces and reputation damage.
