Back in June, Hidden Pineapple, the studio behind once popular Rowi Twitter client for Windows Phone devices announced that they are now working on a better way to do email on Windows Phone. Today, they have released a preview version of Maestro on Windows Phone Store. People who signed up to know more about this app received an email today notifying about the availability. It includes some cool features such as color-coded accounts, Swiping gestures on messages, and Cortana support. Since it is an preview release, you may encounter lots of bugs and crashes. Report it to the developer to make it better.
