Mailbox, from Dropbox (plus 1 GB of space to your Dropbox)

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?
Disclaimer: I'm a maintainer of Sup, which is born on the same idea that tags + good search is much better than folders.
I want to see the number of unread messages in the inbox only. Not the total number. Not an arbitrary number. Not zero. Is that too much to ask? Outlook lets me do it, Mail.app lets me do it. It makes sense. So why not? Why force your beliefs and practices and methodologies on me? I have my reasons for keeping all my read mail in my inbox, and I'm not going to change that for a silly app.

Seriously, you don't have to use Mailbox, no guns were put to heads.
It's nice but has many frustrations in the UI - especially when dealing with large message threads.
There are a number of interface gripes I have, and it sometimes consumes about 1.5GB of RAM, but overall it's the best OSX email client I've used (that's being actively maintained).
( I use Mailbox with my work email and love it )
Mailbox's only distinguishing feature is task-based email. By making it GMail only, there's not really much to set it apart from the official task-based Gmail client (Inbox). Inbox works really well, so I'm not sure what the purpose of Mailbox is at this point.
General IMAP support would be a huge plus.
In contrast, Outlook (previously Acompli) is very stable. It may require more taps to do something like move an email to a specific label, but at least the app performs well and hasn't crashed on me once.
It's just a shame that it's tied to gmail and forces you to use Dropbox. Makes it useless for many of us at work.
