It's not every email, it's just the ones in the main inbox (as opposed to notifications, promotions, social, etc). At least for me, it usually maps almost perfectly with human-sent emails, so it's a good feature because I very rarely check my email manually. It's pretty rare for me to receive more than a couple notifications a week at most.
