Boost customer acquisition and retention by leveraging rewards with Klaviyo and integration

Human reliance on recommendations, whether from friends or online reviews, is well-known. E-commerce has broadened this scope of seeking reviews, allowing potential buyers to access opinions from across the globe. To encourage reviews, incentivizing customers with rewards along with effective communication to promote continued participation is an excellent approach . Carbone, one of our clients, leverages the Flits reward program and integrates it with two Shopify apps to enhance customer retention. Established in 2007, Empresas Carbone offers a wide range of competitively priced hardware products for homes, restaurants, offices, and more.


Carbone Store sought a Shopify loyalty program to offer incentives to customers and communicate with them about Birthday credits, monthly credits, credits for orders, and product reviews via mail notifications.


For sending credit notifications, Flits integrated its API with an email notification platform so the merchant could notify their customers after they received a reward. Carbone store also wanted to send product review-related reward notifications.

For this requirement, all three activities (review, rewards, and email notification) needed to be interconnected. This means once the customer leaves a review, they get X credits and an email informing them about the credits earned on leaving the review. Hence, Flits integrated its API with a product review tool as well.

It is important to note that Flits API is flexible enough to integrate with all reputed Shopify apps.

Flits solution

To develop the solution into a process, Flits integrated with Klaviyo. Klaviyo is a marketing automation platform that automates eCommerce SMS and email marketing to help businesses acquire, retain, and grow their customers by sending marketing emails.

For giving product review credit, Flits integrated with Judge Me, which is an app that lets you collect and display product and store reviews.

By integrating with both apps, the Carbone store could reward their customer for leaving product reviews and then apprise them of the same via email notification.


Setting up a loyalty program and notifications for the same has helped the Carbone store improve its reward redemption rate. Currently, it stands at 38.47 %.

Reward redemption rate = Rewards spent/ Rewards earned *100

They have also received more than 2,000 product reviews in the last 9 months.

Apart from this, their repeat purchase rate is around 25.53%.
