Klaviyo Promo Codes & Coupons September 2025

If your Klaviyo promo code isn’t working at checkout, it’s usually due to issues like code expiration, minimum purchase requirements, product exclusions, or technical setup errors.

Common error messages include “coupon code is invalid at checkout” or “not enough coupon codes are available to send to all recipients.” These often occur if the code has expired, hasn’t been activated yet, or doesn’t meet the store’s restrictions, like only applying to certain products or order values. Sometimes, static codes can be overused or shared too widely, while unique codes may only work once per customer. On platforms like Shopify, codes may only activate at a specific date or after being sent, so testing them before activation can result in an “invalid” message. Double-check that you’re entering the code exactly as received, and review the terms—some codes exclude sale items or require a minimum spend.

Pro tip: Always check the fine print in your promo email and try the code on a non-sale item above the minimum spend to avoid common pitfalls.

Klaviyo itself provides the tools for merchants to create promo codes, but whether a code works on subscription purchases depends on how the merchant configures the code in their e-commerce platform.

Most merchants set up Klaviyo codes to apply only to one-time orders, especially for welcome or first-purchase offers. Subscription products are often excluded from general discounts due to recurring billing complexities and lower margins. If you try to use a code on a subscription and see an error like “code not valid for this product,” it’s likely restricted to one-time purchases. Always check the code’s terms in the email or on the merchant’s site—some merchants may offer special codes for subscriptions, but these are less common.

Pro tip: If you want to use a code on a subscription, contact the merchant’s support before checkout to confirm eligibility or request a subscription-specific offer.

Generally, Klaviyo promo codes cannot be combined with other discounts or already discounted plans—most merchants restrict codes to full-price purchases only.

If you try to stack discounts, you’ll likely see an error at checkout such as “cannot be combined with other offers” or the promo code field will be disabled when a discounted plan is in your cart. This is a common practice to prevent excessive discounting and protect margins. Some merchants may allow stacking for special events, but this is rare and always stated in the promo’s terms.

Pro tip: For the best savings, compare the value of your existing discount with the promo code and use the one that gives you the bigger benefit—sometimes removing the discounted plan from your cart lets you apply the code for a better deal.
