I have a second phone (with a different number via pay-as-you-go sim card) that is my weekend phone. It only has personal email and apps that empower me to create (such as Tumblr) vs. consumption…basically anything with a feed.
In addition, I use two email desktop clients: Sparrow, which includes all email and includes work, then Airmail, which I only have personal email added to encourage me to write to friends. For me, I need that sort of separation to keep me sane moderately disconnected.
I’ve found this the best way for me to separate work from rest.
