Honest limits: this tool runs local syntax & pattern checks only. True deliverability (MX records, SMTP mailbox checks) needs a mail server and is impossible to verify in-browser, so a "valid" address here is well-formed, not guaranteed to exist.

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.

What you can do

How to use Email List Cleaner

  1. Open Email List Cleaner in your browser. No sign-up or installation needed.
  2. Paste your email list into the text area (commas, newlines, semicolons all work), or drop a .txt / .csv file directly onto the upload zone.
  3. Toggle the options: dedupe, syntax validation, disposable-domain filter, and role account filter are all on by default.
  4. Click Clean list. Review the stats tiles and use the tabs to browse valid, invalid, disposable and role addresses.
  5. Accept any typo fixes suggested (e.g. gamil.com to gmail.com), then download your clean list as .txt, .csv, or a full-status report.
