Actually, nowadays, the email is more likely to be read in a timely fashion. Snail mail to congress gets delayed because it's subject to heavy duty security screening before it ever reaches the legislator's office. It may be useful for issues of general concern, but if you're writing about any specific piece of legislation presently under consideration your snail mail may not even reach your representative's office until after the bill has already been voted upon. You're better off phoning.
