Hi,
I have a physical store, and hence a database of my existing customers.
I want to email them all and offer some reward for referring other customers. I cant seem to find anything on this.
I can offer a discount coupon to them and then track the coupon, but this makes it complicated.
Because there is no guarantee that my existing customer will pass on that coupon, or he will use it for himself.
And if they are referring multiple customers, I want to give them multiple discounts.
Is there a way out?

Thanks
