Great so far.

I have wanted an alternative for Mac Mail for a while, and finally decided to try Airmail. I downloaded it for my macbook and iMac, thinking if it works well I might download the iPhone app later. At first i had issues setting up my non-gmail accounts, but I created a ticket in Airmail’s support, and heard back from a guy named Paul within minutes. Over several emails he helped me get my accounts online. Really impressive customer service. I love the way Airmail looks and handles my different accounts too. I’ve only had it for a cuople of days, but I feel optimistic—and if I run into any more trouble I feel confident that I’ll get a speedy reply from support.
