You're going to DOS their offices then. Just write a nice, single email free from spelling or grammatical errors. I've started corresponding with the offices of my congressmen a few months ago, writing a letter whenever some issue comes up that matters to me.

I lay out my case for why the issue is important to me, then illustrate the importance of the issue to larger US society, then I ask what sort of actions or policies the politician is going to take on the issue.

I have gotten a response every single time and while some of the responses have tended towards the more formal, "blow off" type of response, I can tell that someone at the office is at least reading what I've sent them and responding.
