See every featureKlaviyo can send anything. It just can't tell you who to send it to, or when. RetentionLab watches your store and finds the customers about to churn, ready to reorder, or due for a cross-sell. You see them on one dashboard, ranked by the revenue actually at stake, then sync the ones you want into Klaviyo as ready-to-use segments. Your existing flows do the sending. Connect it once and it runs on its own.
Stop guessing when customers are about to churn. ShopLoop analyzes your historical order data to calculate a unique predicted purchasing window for every single shopper. When a customer misses their expected re-purchasing window, ShopLoop automatically triggers a personalized win-back email containing a custom discount code.
