Gmail Unsubscriber vs Smart Delete for Gmail

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.

Smart Delete for Gmail is an extension and web add-on that helps Gmail users remove messages in bulk through pattern-based recommendations and rules. It detects recurring email patterns, uses behavior to create deletion rules, and suggests cleanup opportunities among frequent senders. Users can target senders or subject keywords, queue multiple deletions, and preview matches before acting. Starred and important emails are excluded automatically; deleted messages move to Gmail Trash and remain recoverable for 30 days. The add-on appears in Gmail’s sidebar and is available through Google Workspace Marketplace. Its stated permissions cover the open email’s sender and subject, mailbox searches for defined rules, and moving matching threads to Trash; it says email bodies and attachments are not accessed. Plans include Free at free, Light User at $1, paid once, Regular User at $2, paid once, and Power User at $10, paid once.
