InboxTamer, for the recurring-sender problem

Field notes

The tool scans a selected Gmail range, groups messages by sender, and distinguishes cleanable mail from protected mail before offering deletion. Its built-in safeguards cover starred and important messages, receipts, bookings, security access, and legal documents, while custom rules can inspect subjects, addresses, and attachment filenames. Cleanup runs sequentially with up to three retries per failed batch, and the interface includes recovery through Gmail’s Trash.
