It seems like the concept of list building and Constant Contact clients adding contacts to their CC account would a top priority to CC. With the number of contacts as the basis of its fee structure, helping clients graduate through the levels of that schedule would be a mutually beneficiall goal for both parties.
Right now, we have three subscription forms. One is through CC and the other through Formstacker (from the marketplace). Now we are at a crossroads of adding more subscription forms and it is raising this question on why doesn't CC integrate this as a benefit for tribe and list building? I'm going to be paying $200 via Formstacker for a service that I want to feed my CC contact lists.
