The interface is a little too clean, without boxes it's not clear where you enter text. I suppose after a few emails it will become habit.
I completely agree. For the older generation, it might be a bit confusing to see a compose email page without any visual boundaries. I tested a similar design on a forum I run a couple of years ago and got several complaints from the membership which has an average age of between 40-60.
