GMClean vs MailMop

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.

MailMop is a Gmail inbox-cleaning tool for identifying clutter and managing messages in bulk. It groups clutter by sender and shows message counts, then provides actions such as deleting, blocking senders, unsubscribing, marking messages read, applying labels, and creating filters. Gmail headers are analyzed through the Gmail API; when message content is needed to locate unsubscribe links, processing occurs in the browser rather than on MailMop servers. The service says it handles inboxes up to 500,000 emails, while its FAQ states there is no processing limit. MailMop works with one inbox at a time, but one Pro subscription covers all of a user’s inboxes. Basic is free and includes unlimited analysis, sender statistics, unsubscribe, export, and Gmail links. Pro costs $1.89 a year, billed annually at $22.68/year, adding one-click bulk actions, bulk delete, advanced filtering and labels, and sender blocking. It is available on the web or can be self-hosted for free.
