Hi @Jefw,

Thanks for sharing this question with our community.

While we cannot currently filter by a particular dynamic coupon code in a flow, we recommend using a conditional split or an additional filter for your coupon code reminder/follow-up message. This filter should read what somebody has done > placed order > 0 times since starting this flow. If you’re using a conditional split, the follow-up email should be located down the “yes” path of the split, while the “no” path should contain no other emails (that will exit the user out of the flow). We also have a guide here on this topic. 

I hope that’s helpful.
