There is no marketing filter for gift certificates. Who is most likely to buy one? The person who last bought one. Right now we have 8k people in there with no appointments- some are gift cert buyers, some canceled....its really hard to tell who is who. We tried to hand tag it and it was a massive protect. We just need a gift certificate filter to reach those people and re-market to them.
It would also just be super helpful to know who received a gift cert. Its really hard to tell and we do sometimes use a gift cert as is is under the purchasers profile- if it was sent to someone we need to know.
