Until a short time ago, you had two options if you wanted to contact an elected official: telephone and the mail. In the last several years, e-mail has been added and become the medium of choice. It’s fast, it gets read, and – at least in the U.S. – virtually all elected officials, from town councils to the President, use and welcome e-mail communication.
Any guidelines for writing letters in this section – the style to use, the information to include – apply to e-mail as well. A letter to your Congressman, whether it’s sent through the post office or electronically, should be formal and as well-written as you can make it. A political communication, to be taken seriously, should send the message that you care enough about the subject to take some care in writing about it.
In the days before e-mail, officials generally considered letters more important than phone calls, because they took more thought and effort. A proper e-mail letter carries the same message – this person has really thought about this, and has put some work into sending his opinion.
