Email sometimes works. I emailed my Senator about SOPA and got a direct response. The response was that she was in support of it, which didn't make me thrilled but I got a response. It was sufficiently well thought out and long that I just assume she was inundated and had a canned reply her aids just pasted to everyone and changed the names. A call may have had more of an impact since fielding a call is, after all, more expensive than an email.
