Mine has been disabled almost since I got my Note 3 over a year ago. I only enable it to check something in it if someone asks a question about it (like where is the box to do X) and I can't remember. Then I disable it again.
It's, IMO, about the worst email app I've ever used - and I've been using email since it was private messages on dial up bulletin boards and send and receive programs on private networks. (I wasn't at MIT in 1965, so I never had the [from what I understand very dubious] pleasure of running MAILBOX. I do remember, however, the computer!user form of email addressing used by uucp.)
