I plan on running a SaaS and to setup a number of various plans customers including a free forever plan as well as a few paid plans, I want to be able to restrict certain coupon codes and plans to certain new and existing customers possibly by way of email invitation.
So for new customers they would be able to set up their account and subscription using the email link we send them or for existing customers they could upgrade their subscription using that link. For coupon codes can these be associated to and restricted to certain individual existing customers we choose? Is this possible or do you have a possible work around solution to achieved this.
thanks
