Is There a New Email System?

Mailbox is the only system that I have found that has an app on every platform I use. The snoozing things are observed across platform so if I go to the Mac I'm not going to see my email looking differently to my iPhone because the way that the email is snoozed is very weird and they have to hack around with folders and filters you don't really want to see. Mike says he needs to force himself out of this habit and end up with a better system at the end of it but the first part of that is finding an iOS app that she's happy with.
