Hi,
First of all, I want to generate a coupon that user1 (exsisting customer) can forward to user2 (new customer).
That can be done with Acymailing, and user 1 can forward the mail to the new customer.
So the new customer can instantly use the coupon on the first order.
You could do that by having the coupon generator tag in AcyMailing's integration with HikaShop to support the "access level" setting of coupon. That way, you could restrict generated coupons to guests and "registered" users
This can not work. In the Acymailing integration, I can not set a coupon validity for a certain user group, nor individual user.
Apart from the amount / percentage, dates, you can only set Product, Quota and Quota per user.
So is there no way to prevent the coupon code to be used by user1?
