I used to have remote access to work emails via a browser from home or phone until a while ago, but lost that because of tightening security rather than anything intended to improve my well-being by only being able to access emails when actually in the office.
The reason I miss it most is for being able to check what I'm going back to after a holiday. I was in the practice of quickly checking the number of unread emails in my inbox on a Sunday night before returning to the office. No intention of reading them then - it was just nice to be able to mentally prepare myself for how good/bad/indifferent the first few hours back at work were likely to be. Now I just kind of assume the worst and go in blind first thing Monday morning.
