Well I done it by code. I have 2 promotions, one is invite a friend and other is birthday, both promotions generates a coupon when a customer acomplishes the requeriments. Of course, the customer should receive notification by email. I do it by code but my question is if there is some configuration in konakart that makes it automaticaly, providing a template for each promotion. If not, I think it might be a good improvement. And most if shops owner wants to make more promotions without adding code.
