Works with email lists, subscriber exports, and lead lists
Why email lists need this specific kind of cleaning
Email lists collect duplicates in ways a basic "remove duplicates" won't catch, because the same real inbox can appear written several different ways:
- "Jane@Company.com" and "jane@company.com " are the same subscriber, but look different to most tools
- Stray whitespace from copy-pasting between spreadsheets or forms
- Blank rows left over from exports are removed automatically
Everything runs directly in your browser using JavaScript, your list is never uploaded, stored, or seen by anyone. Close the tab and it's gone, this matters for a list of real people's contact information.
Free to clean lists up to 200 rows. Unlock unlimited rows for a small one-time payment, no subscription. This also unlocks our other CSV tools.
Note: this unlock is tied to this browser. If you switch devices or browsers, use "Already paid?" below to restore it.
