At present Constant Contact is blocked by the U.S. House network, and I assume the Senate network. Every member of Congress has multiple websites and sends bulk and solicited email either from their Office or from their campaign or both. This is a pretty big market. I suggest CC establish a Political Division to study this market and begin catering to it. You need to learn the rules and ethics relative to official business, meet the Franking and Ethics office people and make CC available to all in Congress.
