Setup Guide: How to Send Promo Codes with Klaviyo?

Once a brand experiences rapid growth, maintaining personalized communication that goes beyond "Hi {first_name}" becomes an exceedingly challenging task unless appropriate tools are in place.This is where the right choice of coupon management software and marketing automation tool comes into play.

In this blog post, I will show you how you can leverage Voucherify and Klaviyo integration, building the winning formula for creating and distributing promo codes and other incentives to the right customers at the right time.

What is Klaviyo and how does it work?  

Klaviyo is a marketing automation and customer data platform, empowering brands to offer a more individualized customer experience.

Workflows offered by Klaviyo

With Klaviyo’s automated features such as encouraging repeat purchases, sending purchase reminders and order updates, you have the capability to construct multi-channel customer experiences, streamlining marketing automation with prebuilt workflows such as welcome series, abandoned cart recovery and customer loyalty. But sending plain messages will fall flat if there is no tangible value behind them. This is why you need a robust couponing tool on top of Klaviyo automation.

Why connect Voucherify with Klaviyo?

Contextual messaging is just one piece of the puzzle when it comes to running effective coupon and discount campaigns.

Although Klaviyo offers a range of features to boost customer engagement, it has significant limitations when it comes to coupon management, such as:

  1. The inability to store important coupon details (metadata) such as its value, expiration date, and usage restrictions.
  2. Klaviyo supports only three coupon discount types: fixed amount, percentage and free shipping.
  3. No coupon redemption tracking nor advanced coupon customization tools.
  4. No validation rules to build coupon eligibility conditions.
  5. By default, your options for segment building are restricted to a basic set of customer properties, including city, country, email address, first active. Klaviyo does not offer support for advanced customer metadata features, such as payment method or geolocation.

Don’t get me wrong – Klaviyo is a fantastic tool for engagement and managing customer data, but it can’t excel in everything. This is why you need an external coupon engine to ensure that your offers are targeted and fraud-proof.  

This is where Voucherify steps in, offering comprehensive coupon management options.
