SMTP mailbox checks, CSV upload, and results that stay honest — catch-all is never marked Valid.

SMTP verification

We probe the mailbox, not just the domain.

CSV in, CSV out

Upload a list and export Valid, Invalid, Catch-all, and Unknown.

Catch-all stays catch-all

Unknowns are not guessed Valid.
