In this blog post, we will discuss how to configure email notification using SNS.

What is SNS?

Simple Notification Service or SNS is a web service that sends messages from publisher to subscriber. A publisher can be any event source like CloudWatch or CloudTrail and a subscriber can be SMS, email, http\https endpoints, lambda, SQS etc. Publisher act as message source and subscriber as destination and SNS coordinate the message delivery from source to destination.

When using Amazon SNS, you create a topic and control access to it by defining policies that determine which publishers and subscribers can communicate with the topic. A publisher sends messages to topics that they have created or to topics they have permission to publish to. Instead of including a specific destination address in each message, a publisher sends a message to the topic. Amazon SNS matches the topic to a list of subscribers who have subscribed to that topic and delivers the message to each of those subscribers. Each topic has a unique name that identifies the Amazon SNS endpoint for publishers to post messages and subscribers to register for notifications. Subscribers receive all messages published to the topics to which they subscribe, and all subscribers to a topic receive the same messages.
