I'm sad to hear that Google is discontinuing Inbox; it's been my favourite email app for four years now, and I don't think I'll ever be as comfortable using Gmail after so long.
@earfoldsOh noooo, I use it as well!
@a_puma01 Thankfully we still have a few more months to decide on an alternative. I'm half-considering ending my free Google Apps account and self-hosting my emails again.
