I wish there were a better way to actually get an answer from your rep. These emails really don't work. Even when they come in en masse they don't work. I know people who work for representatives and manage these email accounts. They have filtering rules to pick these sorts of emails up and and throw it in a folder never to be read. Especially those websites that automatically generate the email for you, those are almost guarenteed to not even have a low level staffer see them. Catch some choice lines from the body and straight to spam.

I asked these people how constituents are to reach out toward their representatives for issues that matter to them, and to be honest what they said was that the only way you are going to get a response is if you are representing an organization or a corporation capable of financing advertising campaigns that can influence large swaths of the electorate in question. A single voter will never be answered by a state level or higher rep, if you are lucky you might just get a canned response from the staff outlining the candidate's platform on the issue. If you are a representative from a special interest lobbying group though with thousands in the war chest, that will get you a long phone call or even face time with the representative. This is how the game is played on both sides of the aisle.
