mailtrim
What it is
mailtrim is a free Linux command-line tool for locating and removing inbox clutter. It ranks senders by storage impact, then supports bulk deletion from selected senders or an entire domain; one command can remove 300 or more messages from one sender. A dry-run preview shows the proposed purge before confirmation. Deleted mail goes to Trash and can be restored for up to 30 days. The tool works with Gmail and IMAP services, including Outlook, Fastmail, iCloud, and self-hosted IMAP servers. Gmail setup uses OAuth, while IMAP setup accepts server credentials without keeping the password in local storage. Optional AI features provide inbox triage, natural-language bulk operations, and weekly digests, and are disabled by default. When Anthropic handles those features, subjects, sender names or addresses, and snippets are sent, but not full bodies or attachments. The privacy policy says metadata, tokens, undo logs, rules, and unsubscribe history stay locally, with no analytics, crash reporting, or usage tracking. mailtrim is MIT-licensed and free to use, modify, and distribute.
