My agency deals with a lot of consumer-facing campaigns, most of them in the form of promotional games (e.g. send a cash receipt and win, etc). Most of these promotions stick to 3-4 recipes. While i have seen many great website builders, i have never seen one that offers the possibility to build the entire promotion. So we built Promotiful: https://www.promotiful.com/
