When I sent e-mail to my Senators in Colorado, I always received a real letter in the mail. Many times, it was personal and actually signed. One time, Ben Campbell wrote a personal letter, going in to great detail, his same concerns about the Grand Junction Airport service....stating what he's been upset with and what's he's been trying to do to fix the problem....it was not a mass-mailing letter....it was a specific response to me, personally and, again, signed in ink.
