About the Email List Cleaner

One pass over a messy export that does everything you would otherwise do by hand in a spreadsheet. Whitespace and invisible characters are stripped, addresses are lowercased, display names in angle brackets and mailto: forms are unwrapped, and stray commas and semicolons from a hand-split header are dropped.

Then the removals, each one a switch you can turn off: duplicates, invalid addresses, disposable domains, role accounts, free consumer providers and reserved placeholder domains. The counter beside each switch shows how many rows it would remove before you commit to it.

What comes out is a list you can paste straight into a sending platform, and a separate list of everything that was removed with the reason for each, so nothing disappears without you being able to see why.

Frequently asked questions

No. It is read and cleaned entirely in your browser, and this site has no endpoint that accepts a file. That is the structural reason the promise holds, rather than a policy you have to take on trust.
