Inbox zero was introduced by Merlin Mann already back in 2007. But as time spent emailing hasn’t exactly decreased, it should still be relevant right?
Me and many others keep pointing out that prioritizing is key for any product manager (as well as most other people). Spending more time than necessary sorting through your inbox is definitely not the way to go. It just adds to the stress of constantly juggling tasks and priorities. So while not new, is inbox zero perhaps the solution to reduce your stress level?
