This kind of effort does sometimes rise to the notice of Congresscritters. They get reports form their staff, which may feature counts of constituent and non-constituent communications on specific issues and positions. Things from a service like this go into the "generated" category, not quite "spam" but not trustworthy numbers. It's much more impactful (or used to be anyway) if you get your users to print, hand sign, and individually mail your form letter "this is how i feel about $issue" communications.
