With Amazon Device Messaging, you can send messages to individual users on specific devices. You can update customers on game play, invite them to purchase a related product, or send other messages that create a richer app experience.
Amazon Device Messaging respects users' battery life, so you can, too. Using the Amazon Device Messaging service allows your app to avoid performing polling, a serious battery drain, while not requiring additional power to stay connected—a benefit your users will appreciate.
In addition to providing a best-in-class payload size of up to 6KB per message, Amazon Device Messaging is available at no cost to developers.
