Looking for a mainstream ESP to handle simple opt-in traffic, can manage multiple lists, etc. But must be able to actually inbox at yahoo, aol, etc. Have tried aweber, streamsend, inbox25, pinpointe, 1shoppingcart, verticalresponse, jangomail. So far pinpointe inboxes, but has lousy terms. 1shoppingcart doesn't allow multiple lists from what I can tell. Any other suggestions?
