I've been aggressively filtering my email for years. I unsubscribe from things on the first email. I set my email notification settings to the bare minimum everywhere. I created filters for everything that slips through, down to confirmation emails. Now 95% of the emails I get are written by a human or otherwise wanted. I don't need categories, because everything I get is relevant.
