Gnuke

Gnuke is a Chrome extension for cleaning up Gmail. Click the bomb button on any email and Gnuke unsubscribes you from that sender and moves every email they ever sent you to Trash. Clean up lists every newsletter and promo sender in your inbox, biggest first, so you can mass unsubscribe and bulk delete the lot in a few minutes.

The videos here are short and cover one feature each: deleting all emails from a sender, unsubscribing from newsletters you never open, blocking senders who ignore your unsubscribe, and cleaning up Gmail on your phone.

Your mail never leaves your browser. Gnuke is free for 10 senders a month.
