Amazon Simple Notification Service (SNS) is a push notification service that allows users to send messages to large numbers of recipients like mobile devices or email. The Mule SNS Connector allows connecting to SNS to perform operations like creating topics, subscriptions, and publishing messages. To publish a message, a topic must first be created in AWS SNS and the connector configured with credentials. Then a publish operation can be used to send a message to subscribers of that topic.

Amazon Simple Notification Service (Amazon SNS) is a fast, flexible, fully managed push notification service
that lets you send individual messages or to fan-out messages to large numbers of recipients. Amazon SNS
makes it simple and cost effective to send push notifications to mobile device users, email recipients or
even send messages to other distributed services.
With Amazon SNS, you can send notifications to Apple, Google, Fire OS, and Windows devices, as well as to
Android devices in China with Baidu Cloud Push. You can use SNS to send SMS messages to mobile device
users world wide. Beyond these endpoints, Amazon SNS can also deliver messages to Amazon Simple
Queue Service (SQS), AWS Lambda functions, or to any HTTP endpoint.
