In their own words
Gmail Unsubscriber
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.
InboxSweeper
InboxSweeper is a free, open-source tool for clearing old promotional mail and newsletters and unsubscribing from mailing lists. It supports Gmail fully; Yahoo and other IMAP inboxes are experimental. Choose among three sweep modes: Sloth targets mail older than two years, Normal mail older than one year, and MadMax includes recent promotional mail. Their respective run caps are 25, 50, and 100 senders. Before moving messages, sweeps show counts; financial, security, payment, receipt, and government mail is protected. You can unsubscribe, move selected messages to Trash, or report senders as spam. Trash messages are described as recoverable for about 30 days. One-click and mailto unsubscribe options are supported; web-link-only options are flagged for manual handling. The tool runs on your computer and says it does not upload mail, credentials, or tokens. It offers a local browser interface, Windows executable, terminal CLI, and AI-agent instructions. It uses a scoped app password rather than Google OAuth, with credentials stored in macOS Keychain or a locked file.
