Dispatch has become my go to email app, not only on iOS, but across all platforms. The ability to make every single email actionable right from the get-go is invaluable for my productivity.
If youre looking for email application that allows you to get out of your inbox and where you need to be as effectively and efficiently as possible, then look no further than Dispatch. I cant recommend it enough.
