Webfreeglobal

A free, open-source web app that validates and cleans email lists entirely in the browser, detecting and removing disposable, role-based, invalid, and duplicate addresses (including Gmail dot-variant duplicates). It keeps list data on the user's device instead of uploading it to external servers, for email marketers and organizations that maintain mailing lists and need client-side, privacy-preserving cleaning.
