A shopper asks to hear when a product returns, then the alert can be sent while that buying interest is still recent. Back In Stock - Restock Alerts supplies the notification request event, and Zapier can pass it to Mobile Message for a plain text confirmation or follow-up. This gives store teams a direct way to acknowledge the request and keep the customer informed through SMS.

The available trigger is New Stock Notification Request. It can start Mobile Message's Send SMS action, using the customer's phone details and product information available from the request. You can also use Create Contact if the shopper is not already recorded, or Add Contact to List when you maintain a specific restock audience. The message should explain what the request means and what the customer can expect.

This app's supplied event covers a request to receive a notification, not the later moment when stock actually returns. The Zap therefore cannot claim that a product is available unless another listed event supplies that information. It creates a useful request acknowledgement through Zapier, without pretending to be a two-way inventory connection.
