What is your favorite mail app on iOS?

Take into consideration that my main emails are hosted on Rackspace so I need IMAP access, not only service-specific access.

Spark has replaced the default mail client on both iPhone and Mac for me. Excellent UI and UX, seamless sync, and free.

I haven't used any other iOS mail clients since I made the switch to Airmail. The customisation options are just insane. I love it.

You're able to archive multiple emails you're not likely to read, which saves a lot of inbox management. The generated user profiles with statistics are pretty nice too.

Inbox by Google

Great iOS app, but no Mac app for it. Love the UI and the fluidity of the User Experience!

Supercharged emailing with space-age features

Must be newton for me across all platforms! What I really like: - all your email accounts in one newton account - UX - Regular updates and innovative features (like looking up LinkedIn information on the sender and displaying it to you) What you should consider: - all your email accounts in one newton account (security) - it's not free
