Smart Delete for Gmail vs Trimbox

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.

Trimbox helps Gmail users reduce unwanted mail by finding mailing lists and older messages, then offering tools to unsubscribe, delete, and block future messages. Users can unsubscribe from a list with one action; if the list requires a formal request, Trimbox can send one. To clear older mail, users can delete messages from a sender in one action. Those messages move to Trash and are permanently removed after 30 days. Trimbox can also create editable Gmail filters to block unwanted senders. The maker says email data stays on the user’s device and is never shared, and that Trimbox is verified by Google. The service needs access to a Gmail account to find mailing lists and delete old junk mail. Trimbox is available as an extension, in a browser for Gmail, and as a mobile app on Android and iOS. The App Store listing says users can connect unlimited email accounts, but the free plan covers the first 10 unsubscribes; a subscription unlocks unlimited unsubscribes. The listed free plan is free.
