Email List Cleaner
Paste or upload a list — remove invalids, dupes, and disposables.
How it works
Clean an email list in your browser
Paste addresses or upload a .txt / .csv → click Clean list → we normalize case, drop empty lines, invalids, known disposables, and duplicates. Nothing is uploaded for cleaning — download CSV or email yourself a summary when you’re done.
Results appear here after you click Clean list.
