I always assumed Gmail bloat came from large attachments. Turns out 3 senders were responsible for 30% of my inbox — thousands of tiny emails I'd never thought to clean up. I built mailtrim to surface this pattern: - ranks senders by actual storage impact (not just count) - confidence scoring on what's safe to bulk-delete - 30-day undo on everything — nothing is permanent by default - runs entirely locally, no email data leaves your machine Free, open source (MIT). No subscription, no backend. One friction point upfront: Gmail API setup is one-time, ~15 min. After that it's just `mailtrim stats` and `mailtrim purge`. Keen to hear feedback on the confidence/safety model especially — that's the part I'm least sure I've got right. https://github.com/sadhgurutech/mailtrim

Could you build this?
Yes It interacts with the standard Google Gmail REST API via OAuth to inspect message/thread sizes and aggregate storage usage into a breakdown.
