We have added support to Amazon SNS for large topics (more than 10,000 subscribers) and authenticated delivery to MPNS (Microsoft Push Notification Service).

Large Topics: SNS already supports broadcast notifications with SNS Topics, which are ideal for breaking news, announcing flash deals, and announcing in-game events or new features. Today we are lifting the limit of 10,000 subscriptions per SNS topic; you can now create as many as you need and no longer need to partition large subscription lists across multiple topics. This has been a frequent request from AWS customers that use SNS to build news and media sharing applications.

There is an administrative limit of 10 million subscriptions per topic, but we'll happily raise it if you expect to have more subscribers for a single topic. To raise your limit, please submit a Service Limit Increase request for Amazon SNS using the form here.

Authenticated Delivery to MPNS: Microsoft Push Notification Service (MPNS) is the push notification relay service for Windows Phone devices prior to Windows 8.1. SNS now supports authenticated delivery to MPNS. If you require this functionality for devices that run Windows 8.1 and above, please also consider using Amazon SNS for Windows Notification Service (WNS).
