ClearInbox vs Gmail Unsubscriber

ClearInbox is a web email-cleanup app that can also be self-hosted with Docker. It groups messages into smart folders such as newsletters, social, shopping, finance, travel, old mail, and large mail, then suggests archiving or deletion. Mailing lists can be unsubscribed individually or in bulk where RFC 8058 one-click support exists. Auto Clean rules move, archive, delete, star, or mute messages on schedules or when new mail arrives. A sender screener holds first-time senders for approval or rejection, and users can block senders or domains. The web client supports composing, replying, forwarding, searching, labeling, starring, and pinning across multiple connected accounts. Supported providers include Gmail, Outlook, Microsoft 365, Yahoo Mail, iCloud Mail, AOL, Fastmail, Exchange, and IMAP services. The maker says cleaning uses headers and metadata, full bodies are not stored, and connections are encrypted.

Gmail Unsubscriber is a free, open-source Google Apps Script for unsubscribing from unwanted newsletters and other bulk email in Gmail. It looks through bulk messages for unsubscribe links and opens them; when a sender requires an email to unsubscribe, the script can send one to a special address. Setup involves copying a Google Sheet to Drive, configuring the script from Gmail's menu, and allowing it to access your Gmail account. Messages with the configured Gmail label are processed automatically, typically within 10–15 minutes, and the script records activity in the Sheet. You can add messages to the queue from Gmail on the web or mobile apps, Microsoft Outlook, or Apple Mail by applying the label or moving a message to the Unsubscribe folder as appropriate. The project uses Gmail labels and a Google Sheet and carries an MIT License. Its maker says the script runs without storing or uploading data and does not require access to a third-party service. The listed free plan costs nothing.
