If I use the same coupon placeholder variable in multiple locations within a single email, will Klaviyo populate the same coupon code in all locations within this email?
Yes. Klaviyo will store every coupon code until it expires (up to 1 year). This means if you use the same placeholder variable multiple times in the same email, the same code will populate in all locations. This also means if you have a multi-email automated flow series, and you send someone a coupon code in Email #1, you can use the same coupon placeholder in Email #3 and we’ll give your customer the same exact code (unless the code has already expired).
