The way we’ve solved this problem for several customers in the past is to have multiple Coupon Carrier accounts, each one connected to different email lists.
You can then subscribe people to different lists depending on which discount they should get. That way you can also import different sets of codes into each coupon carrier account.
Note! It's important to know that you can only have one Coupon Carrier account monitor one email list at a time. If another account is configured to monitor the list it will remove the other connection.
You can also link multiple Coupon Carrier accounts. This will allow you to quickly switch and transfer credits between them.
You can create additional accounts at CouponCarrier.io.
