In their own words
Smart Delete for Gmail
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.
