Which protocol is commonly used for email notifications in AWS?

Amazon Simple Email Service (SES) is specifically designed for sending email notifications and managing email communications within AWS. It provides a highly scalable email sending service that enables businesses to send marketing, notification, and transactional emails. SES simplifies the complexities involved in sending emails, allowing developers to send emails directly from their applications or websites through a simple interface.

SES also offers features like content personalization, email sending configuration, and analytics capabilities to track email delivery and engagement, making it a comprehensive solution for email notifications. This focus on email delivery and management distinguishes it from other services like Amazon Simple Notification Service (SNS), which is used for various types of notifications but does not specialize in email.

Using SES is particularly beneficial when applications require high deliverability and management of email routing, ensuring that notifications are reliably sent to users.
