About Email List Cleaner
Email List Cleaner is a free browser tool by Digital Heroes that cleans and validates email lists without uploading anything. Paste any list, and it strips whitespace, removes duplicates, checks email syntax, flags disposable domains (Mailinator, 10MinuteMail and 100+ others), filters role accounts (info@, support@, noreply@) and suggests typo fixes for common domain misspellings. Everything runs locally in your browser. No server, no sign-up, no limits.
