What GMClean is
GMClean is a free, self-hosted web tool for scanning inboxes, classifying email, unsubscribing in bulk, deleting messages, and exporting data. It fetches headers such as subject, sender, and List-Unsubscribe rather than downloading email bodies. The tool supports up to 10 Gmail, Outlook, or custom IMAP mailboxes at once and 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 use for ambiguous cases. It supports one-click RFC 8058 unsubscribe and bulk unsubscribe; bulk deletion is processed in batches of 500 messages. Exports include selected subscriptions with resubscribe links and scanned emails in CSV format. GMClean stores app data in browser IndexedDB and says it has no cloud database or telemetry. Credentials are encrypted with AES-256-CBC before storage, and setup requires an ENCRYPTION_SECRET described as an AES-256 key. The project documents running it with npm, Docker, or Docker Compose. It supports app passwords and OAuth2 for Google and Microsoft, and is licensed under MIT.
