GoodByEmail vs mailtrim

GoodByEmail analyzes an exported inbox to show which senders use storage and help users decide what to clean up. Users import an MBOX or Outlook PST file, then filter or sort senders by storage, email count or last received date. The app can identify mailing-list senders and supports one-click unsubscribing. It does not scan or delete messages automatically: users export their inbox and remove selected emails in their email client. The maker says mailbox processing happens locally, without uploading or storing email content, metadata or mailbox statistics on its servers. Scanning can work offline after an online login unlocks the app. The free version shows unordered results for everyone who has emailed the user; actionable cleanup insights require a license. Paid options include Lite at $9.99 a month, Plus at $14.99 a month and Pro at $19.99 a month. A Perpetual license costs $199 as a one-time purchase. The platform list includes macOS, Windows and self-hosted.

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.
