Nice review from Viticci. I will say that the UI looks kind of interesting, but I just don’t see the benefit over using the native Mail app — there are some nice touches, but that’s about it.
Why, this is why:
It’s also worth noting that, because this is a third-party client, iOS apps that embed mail views will still fall back to Apple’s Mail — the same that happens with third-party browsers.
Until I can change the default email app, it’s not worth using a different email app.
