What does Amazon SNS use for delivering messages?

Amazon Simple Notification Service (SNS) utilizes multiple communication protocols to ensure messages are delivered efficiently across different platforms and devices. This flexibility allows developers to send notifications through various channels, such as email, SMS (text message), and push notifications to mobile devices. By supporting different protocols, Amazon SNS can cater to a wide range of use cases, making it versatile for both application-to-person and application-to-application messaging.

For instance, when developing an application, a developer might want to notify users via SMS for immediate alerts while also needing to send emails for detailed reporting. The ability to use multiple communication protocols allows for a seamless integration of notification methods that can enhance user engagement and ensure that important messages reach users through their preferred communication channel.
