Boxer is the best it can be - Apple must change
I have both Boxer and the built-in mail app running. I get push notifications from the built in app and use Boxer to manage my mail. This is Apple's fault, not boxers. We all need to push Apple to allow a replacement mail app
App is not the best it can be! It needs a built-in web browser! Who wants to have to go back and forth to read links contained in emails?
Add a built in browser and make sure it has Share Extensions for it. Open in Safari alone simply won't cut it!
Do this and you will truly have the best email app.

Why does the gmail app work with push and boxer does not?
