Notification Hubs can be integrated into any back-end, whether it is on-premises, in the cloud, or based on Microsoft.NET. This makes it easy to update your mobile app and engage with your customers. Tags allow you to send push notifications to all devices at once, or only specific customer devices. Tags allow you to segment customers by activity, interest, location or preference. This allows you to deliver the right content at the right moment. The templates feature in Notification Hubs allows you to send localized notifications to your customers, so that you can speak to them in their native language. Templates eliminate the need to create hundreds of tags or store the localization settings of each customer.
