My exact gripe with nearly all of the new wave in email clients. I'm aware most people are OK with Gmail, but I'm not--surely IMAP is worth supporting too!

A lot of people use Gmail. A lot of people use iOS. The Gmail iOS client is pile of shit. That's an opportunity if I ever saw one.

Mobile email is hard. Those old standard email protocols don't cut it. Now, if you're willing to hand over your IMAP or POP3 username and password to Microsoft or RIM, they'll be happy to run your private email through their servers to your phone.

Edit: What's with the down votes?

Is it because I said the Gmail iOS client is a piece of shit? Well, it really is unreliable and unusable garbage. If it wasn't then that's what we all would be using.

Is it because I said mobile email is hard? Well, it is. That's why everyone here is looking for a better mobile email client.

Is it because I said IMAP and POP3 don't cut it? There's never been a remotely decent mobile IMAP or POP3 client. If there was, that's what we'd all be using.

It's 2015. Email has been around for 30+ years and everyone uses it, yet it remains an unsolved problem for many people.

IMAP IDLE works fine for me. Mail notification within milliseconds of arrival.

What do you feel is broken?

The folder analogy is completely broken; tags have shown to be much more useful.

Disclaimer: I'm a maintainer of Sup, which is born on the same idea that tags + good search is much better than folders.

Just use Outlook. They have apps for iOS and Android now.

And IMAP! I'm actually really impressed with Outlook. I signed up the other day.

And ActiveSync!

It also supports iCloud

You're certainly free to make an email app too, and you can make it support anything you'd like. Google isn't stopping you.

Cloud Magic handles pretty much everything (except POP3) and has much of the same UI of Mailbox.
