What mailtrim is

mailtrim is a free, Linux command-line tool for finding and removing inbox clutter. It ranks senders by the storage their messages use, not just by message count, so you can identify which senders take up the most space. Its purge command can delete messages from selected senders or target a sender domain; a dry-run preview lets you review the proposed deletion before confirming it. 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 servers. Gmail connects through OAuth, while IMAP setup uses server credentials and keeps the password out of local storage. Optional AI tools provide inbox triage, natural-language bulk operations, and weekly digests, and are off by default. When Anthropic handles AI requests, mailtrim sends subjects, sender details, and snippets, but not full message bodies or attachments. Its privacy policy says email-related data is stored locally and that the tool has no analytics, crash reporting, or usage tracking. The repository describes mailtrim as MIT-licensed. The free plan costs nothing, with no subscription or API key required for core commands.

Who it suits

mailtrim suits Linux users who want a command-line way to find high-storage senders and clean up Gmail or IMAP inboxes in bulk. It may also suit users who want optional AI triage or digests, provided they are comfortable with the stated data sent to Anthropic when cloud AI is used.
