Great improvements!!

UPDATE: below is the review from when this app was released and Im happy to say that they did add alias support and so many more features! Its my favorite email app now. The way they do signatures is AWESOME. And you can add people to you iPhone contact list! I have no idea why other email apps cant do this.

There are a couple of things that need fixing like background refresh. I get the notification that theres new email but it still has to fetch the email when I open the app.
--------------------

Theres some good stuff going on here. The Apple Watch is probably one of the best. But if you need email alias support, this app is a non-starter. Hopefully theyll add soon.
