GMClean vs GoodByEmail

GMClean is a free, self-hosted web tool for scanning email headers, classifying messages, unsubscribing in bulk, deleting email, and exporting data. It works with Gmail, Outlook, and custom IMAP mailboxes, with up to 10 mailboxes connected at once. GMClean fetches headers such as sender, subject, and List-Unsubscribe details without downloading message bodies. It can scan INBOX, Spam, Promotions, Trash, and other IMAP folders. Inbox analysis includes a 0–100 health score based on five weighted factors, sender insights, and email age distribution. Classification uses heuristic rules, with optional Gemini assistance for ambiguous cases. Users can unsubscribe with one click using RFC 8058 support or unsubscribe in bulk; bulk deletion runs in batches of 500 messages. Exports include selected subscriptions with resubscribe links and scanned emails in CSV format. The project documents deployment with npm, Docker, or Docker Compose. It says app data stays in browser IndexedDB and there is no cloud database or telemetry. Credentials are encrypted with AES-256-CBC before storage, and setup requires an ENCRYPTION_SECRET. The repository is MIT-licensed.

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.
