Here's how it works: you use PopVox to communicate with Congress, sending support or oppose messages which are publicly tallied so all can see which way any given Congresscritter's distric was leaning. This tool then shows you, bill by bill, whether your two senators and congressperson voted the way you told them to through PopVox.
If you contact them some other way, PopVox can't possibly know that (nor can anyone but your congresscritter, so there's no accountability), so it's useless without an account.
