New to Klaviyo. I’ve integrated it with Shopify. I set up a new sign-up form and had it link to a list that has double opt-in.
I also set it up to work with unique Shopify coupons codes. However, the coupon code appears when the user hits “subscribe” which means that the user never has to opt in to the list to use the coupon code.
How can I fix this so that the user only received the coupon code after they have opted in?
