You might want to fix the glaring typo "Re:Inveting email" at the top of the page.

As someone aptly mentioned though, the problem is you are just redesigning the email inbox and giving it some quick reply buttons (ala the Gmail canned responses).

I suggest you take a look at AOL's Alto for an example of something that is trying to tackle something similar largely through UX design. http://thenextweb.com/apps/2012/10/18/aol-alto-email-applica...

All that being said, the design is cool. And you have a kickass domain name.
