# Set up notification rules for back-in-stock alerts
Use Notification rules to control *when* subscribers receive alerts and *how* they’re saved in Shopify. These rules help you avoid sending the wrong alert to the wrong customer—and keep your data clean.
## Access notification rules settings
Steps:
1. From the XFlow dashboard, navigate to the **"Notify me" widget settings**.
2. Select the **Others** tab.

## Available rules
### Enable location-based notifications (by country)
Send alerts **only when the product is restocked at the location customers subscribed to**.
⭐ Tips:
* Useful when you manage **multiple warehouses in different countries**.
* Keep this **off** if all locations ship globally or you don’t manage inventory by country. In that case, all locations share the same back-in-stock alert.
### Create Shopify customer
Automatically create a **Shopify customer profile** for each subscriber. [*Learn more about Customers*](https://help.shopify.com/manual/customers)
👍 Best for:
* Stores planning follow-up campaigns
* Merchants who want subscriber data inside Shopify.
