 # Send notifications to your app's customers
 
+> [!IMPORTANT]
+> Push Notifications in Partner Center were formally deprecated at the end of December 2024. For an alternative notification experience, see [Microsoft Azure Notification Hubs](/azure/notification-hubs).

 Engaging with your customers at the right time and with the right message is key to your success as an app developer. Notifications can encourage your customers to take an action, such as rating an app, buying an add-on, trying a new feature, or downloading another app (perhaps for free with a [promotional code](generate-promotional-codes.md) that you provide).
 
 [Partner Center](https://partner.microsoft.com/dashboard) provides a data-driven customer engagement platform you can use to send notifications to all of your app's customers, or only targeted to a subset of your app's Windows 10 or Windows 11 customers who meet the criteria you’ve defined in a [customer segment](create-customer-segments.md). You can also create a notification to be sent to customers of more than one of your apps.
