Push notifications are critical to craft engaging app experience and increase usage and user interest. Windows Azure Notification Hubs support multi-platform push with Windows, iOS, and Android, publish/subscribe routing to particular groups of users or devices, and low latency broadcast to millions of devices. Join us to learn how to use Notification Hubs to target millions of devices at once and single targeted users with just a few lines of code. Easily provide push notification support for Windows, Windows Phone, iOS, and Android, easily send broadcast messages to all users or targeted messages to specific users, start free, scale up and down as needed.
