Coupons in template
If you have already created the coupon pool, you can use them in email templates in order to give 1 unique coupon to each customer. It is provided by the use of placeholder {{coupon_value_coupon-name}}, where the coupon-name is the name of the coupon pool you want to use.
If there is not enough of coupons in the pool, no email with the template including placeholder for such empty coupon pool will be sent!
The HTML template editor whispers the placeholder when you start writing the name.
In Drag&Drop editor, click on Merge tags
and then select your coupon pool.
