Getting started with coupon codes in Klaviyo

Hey there!

Once you create that coupon, you’ll just plug in that coupon name to this code in your email:
 

{% coupon_code 'CouponName' %}

When you click preview, it should show as COUPONNAME-Preview and you’ll know you are all set! If it shows as does not exist then you might not have your coupon name plugged in correctly.

Hope that helps!

Thanks :)

{% coupon_code 'CouponName' %}

Thanks :)
