Detail King aimed to increase repeat purchases, as repeat revenue was essential to its growth. However, targeting customers for replenishment presented challenges due to their extensive product range and diverse customer base. This made it difficult to identify the optimal time for follow-ups, as understanding when each customer might need to restock was complex.
The team recognized that even a modest increase in repeat customers could greatly enhance revenue. Previously, they relied on Klaviyo’s standard Replenishment flow, which lacked the ability to predict the best timing for engagement or provide a seamless buying experience. The flow treated all customers the same, overlooking the fact that while some products last car enthusiasts a few months, professional detailers may require replenishment within weeks.
What’s more, after clicking the call-to-action (CTA), customers were taken through the standard shopping flow—from the product page to the cart and finally to checkout. This approach caused Detail King to miss out on revenue opportunities by not making it easier for customers to make repeat purchases.

With Relo’s predictive reorder feature, Detail King targeted customers at just the right time using Klaviyo emails based on their purchase history. Each customer received a customized message based on what they bought, when, and their buying history with Detail King. Curious how it works?
Detail King connected Relo to their Shopify store, allowing them to forecast when customers might need to reorder products. These predictions consider the product last purchased, quantity, past order patterns, and other relevant data points.

As a final touch, Detail King also added Relo’s Magic Cart feature to simplify the checkout for customers. Magic Cart offers a mobile-friendly, personalized landing page that enhances the shopping experience by being:
