This is kind of annoying to do in practice: it's slow, it might result in your email arriving in the wrong person's inbox, etc. Using Rapportive, all you have to do is type each guess into the To: field, and Rapportive will immediately look up that email address and give you the results.
I discovered this in the best possible way - by accident. Use it and enjoy!
