I have tried almost every legitimate iOS email app. Ive always found the Mac Mail iOS app to be sub par and REALLY SLOW.
No kidding - Easilydos Email app is the answer. Its enough customization without feeling overwhelmed. Additionally - they dont force you to use all their features. Ive never been fond of snoozing or sorting email items for later dates - I have a small business and just need a fast email that can do multiple accounts. This is the one.
