Is it something that people could actually benefit from? I would imagine it could only be used by people reading personal emails. But why would you speed read them? Business emails might include lists, images, urls and this thing would break horribly. In my opinion, emails by me are rarely read end to end (except for personal emails) and I usually just skim through them to get the general idea and then read on the specifics that I care about.
