Inbox Zero: The AI Method

1. Triage first — AI sorts into: Urgent / FYI / Waiting / Archive
2. Batch process — handle all similar emails at once
3. AI drafts — use suggested replies for routine responses
4. Snooze strategically — get non-urgent emails out of sight
5. Unsubscribe ruthlessly — use AI to identify low-value senders
