This filter catches most newsletters with very few false positives: `contains text "unsubscribe"` Most important emails don't contain "unsubscribe," but newsletters are required to include it by law. I added some other things to the filter like `from:noreply`, but my primary inbox only gets a few emails per day, while my promotions and updates inboxes get many more emails.
