Q&A for How to Write a Letter to Your United States Senator

Use "The Honorable Senator Joseph Blowhard."

It's possible that they may ignore it, but then again, it costs essentially nothing to write them a letter. Letting your senator know what you think gives them an idea of what their constituents want, and who knows, maybe a lot of other people with your views also wrote a similar letter. Your letter combined with all of these may make them take a more moderate stance on the particular issue that you're writing to them about.

Instead of contacting them online, you can mail a letter through the US Postal Service and not include your phone number in it.

Writing by hand is acceptable, but a typed letter might be taken more seriously.
