Creating an SNS topic and subscribing through email in AWS is a straightforward process that begins by logging into the AWS Management Console and navigating to the Simple Notification Service, commonly known as SNS, from the list of available services.
Once you reach the SNS dashboard, you start by selecting the Topics section and clicking the Create topic button to generate a new notification channel. You can choose the Standard topic type, which is suitable for most general-purpose messaging scenarios, and then enter a descriptive name for your topic so it can be easily identified later. After providing the name and reviewing any optional settings such as display names or encryption options, you proceed by clicking Create topic, which takes you to the topic’s details page.
From here, you initiate the process of email subscription by selecting the Create subscription option, which opens a form where you must choose Email from the protocol dropdown menu. In the endpoint field, you type the email address where you want the notifications to be delivered, ensuring it is accurate because SNS sends a confirmation message to that address.
After clicking Create subscription, AWS immediately sends a confirmation email containing a link that must be opened for the subscription to be activated. When the user clicks Confirm subscription, the status in the SNS console changes from Pending confirmation to Confirmed, indicating that the email endpoint is now successfully subscribed to the topic.
To verify that everything is functioning correctly, you can publish a test message by selecting the Publish message option on the topic page, entering a subject and message body, and sending it. Within a few moments, the message should appear in the subscribed email inbox, confirming that the SNS topic and email subscription are properly configured and ready for use in notification workflows, automation tasks, or application-driven alerts.
