What they did
In a Cowork project with the Gmail connector, he asked Claude Sonnet to review his archivable label and list newsletters safe to leave, without acting yet. Claude quizzed him with multiple-choice recommendations, then used the Chrome extension and a JavaScript function it wrote to click Unsubscribe in Gmail.
How it went
Claude unsubscribed from 21 newsletters in about five minutes and suggested marking any that resurfaced as spam.
Worth knowing
Cowork needs a paid Claude plan; he used Claude Pro at $20/month and kept a list-first, no-act-yet prompt.
