Gmail Unsubscriber vs mailtrim

Gmail Unsubscriber is a free, open-source Google Apps Script for unsubscribing from unwanted newsletters and other bulk email in Gmail. It looks through bulk messages for unsubscribe links and opens them; when a sender requires an email to unsubscribe, the script can send one to a special address. Setup involves copying a Google Sheet to Drive, configuring the script from Gmail's menu, and allowing it to access your Gmail account. Messages with the configured Gmail label are processed automatically, typically within 10–15 minutes, and the script records activity in the Sheet. You can add messages to the queue from Gmail on the web or mobile apps, Microsoft Outlook, or Apple Mail by applying the label or moving a message to the Unsubscribe folder as appropriate. The project uses Gmail labels and a Google Sheet and carries an MIT License. Its maker says the script runs without storing or uploading data and does not require access to a third-party service. The listed free plan costs nothing.

mailtrim is a free, MIT-licensed Linux command-line tool for finding and clearing inbox clutter. It ranks senders by storage impact, then lets users bulk-delete selected senders or an entire domain; one command can remove more than 300 messages from one sender. A dry-run preview shows the proposed deletion first, and deleted mail remains restorable from Trash for up to 30 days. It works with Gmail and IMAP services such as Outlook, Fastmail, iCloud, and self-hosted servers. Gmail uses OAuth, while IMAP credentials do not retain the password locally. Optional AI tools provide triage, natural-language bulk operations, and weekly digests, but are disabled by default. When Anthropic handles AI requests, subjects, sender details, and snippets are sent, not full bodies or attachments. Metadata, tokens, rules, and undo logs stay under ~/.mailtrim/, with no analytics or usage tracking.
