How Shopify Wishlist Price Drop and Back-in-Stock Alerts Work
Wishlist product alerts notify Shopify shoppers when the reason they postponed a purchase changes. A price-drop alert responds to a lower price, a back-in-stock alert responds to restored availability, and a low-stock alert warns that a saved product is approaching a configured inventory threshold.
With TValue: Wishlist, these are separate automations. Each flow has its own trigger and email template, so the message can match the event instead of sending the same generic reminder for every situation.

A product alert works because something relevant changed after the shopper saved the item.
