Let me walk you through what happens when you add a Gmail account and then share my first impression of Mailbox.
My first impressions are amazingly positive - this is definitely been worth the wait and anticipation.
Mailbox helps you achieve what I believe is the near impossible - an empty mailbox! I don’t mean that everything is deleted but filed and organised for later life or use.
The touch interface with gesture control is amazing - I love the really nice slow or fast swipe with different meaning.
Mailbox in my opinion is how email should be used!
