Using Amazon SNS for application-to-person messaging - Amazon Simple Notification Service

Using Amazon SNS for application-to-person messaging

Amazon SNS application-to-person (A2P) messaging delivers notifications and alerts directly to your customers' mobile devices through SMS (Short Message Service). You can send push notifications to mobile apps, text messages to mobile phone numbers, and plain-text emails to email addresses. You can also use topics to reach multiple recipients at once, or publish directly to individual mobile endpoints for personalized communication.

This topic explains how to use Amazon SNS for user notifications with subscribers such as mobile applications, mobile phone numbers, and email addresses.

An overview of how Amazon SNS supports application-to-person (A2P) messaging by allowing publishers to send notifications directly to customers. It shows two primary ways of distributing messages: direct publishing to individual endpoints (such as email addresses, phone numbers, or mobile apps) and topic-based publishing, which sends messages to multiple subscribers at once. The subscribers, represented on the right, can receive notifications through push notifications, text messages, or emails, providing flexibility for different use cases.
