Currently 303 out of 540 members of Congress have e-mail addresses. When e-mailing members of Congress, keep in mind to be formal and to the point or your letter may be ignored. "Your letter should go to your Senator or Representative and should be no longer than one page, two brief paragraphs are best. Identify yourself, your affiliation, and your major concern in the first paragraph. You should describe why the concern is important and worthwhile in the second paragraph. End with your postal address.
Keep it concise!"
