MailMop

MailMop is the only open-source, free, privacy-first Gmail cleaner that let's you quickly declutter your inbox without compromising your privacy.

MailMop analyzes your emails locally (without your emails ever leaving your device) to tell you exactly which senders are cluttering your inbox. Then, you can use one-click actions, like bulk-delete, unsubscribe, and mark-as-read to clean them up in seconds.
