I truly believe in a work email that can ONLY be accessed at work. Wanna send me stuff related to work? Perfect, here's the email. I'll access it and get back to you once I'm clocked back in.

I think of email like regular mail more than text. It's on the receiver to schedule the time they look at it. 

I have my work email on my phone but don't get any notifications so I only look at it if I want to.
