Email tools shouldn't guess.

Every email verifier faces the same awkward truth: some mailboxes simply can't be confirmed from the outside. Catch-all domains accept everything. Some servers throttle or time out. The common industry answer is to paper over that uncertainty with a confidence score and call the list "clean."

cleanify was built the other way around. It runs the real checks — syntax, DNS, MX records, live SMTP conversations — and reports exactly what they showed, including when the honest answer is Unknown. You get fewer comforting illusions and a list you can actually defend.

It's a deliberately small, private product: your uploads stay in your account, the verification credential never leaves the server, and the interface is built to be read at a glance at 50,000 rows.
