Amazon Simple Notification Service (Amazon SNS) is a fully-managed messaging service that supports application-to-person (A2P) workloads, including mobile text messaging (SMS). Now, when using Amazon SNS to send SMS to your customers, you can set a principal entity ID and a message template ID, as Amazon SNS message attributes.
