Here is the blueprint for an effective letter that I found that makes sense to me:
- Say why you are writing and who you are. List your credentials so the Congressperson knows he is dealing with a constituent, what your angle is. (If you want a response, you must include your name and address, even when using email.)
- Provide more detail about why you are writing. Be factual not emotional. Provide specific rather than general information about how the topic affects you and others. If a certain bill is involved, cite it whenever possible.
- Close by requesting the action you want taken: a vote for or against a bill, or change in general policy.
