An ecommerce company’s two-tier web application on Amazon EC2 is seeing increased traffic and delays in sending marketing and order confirmation email. The company wants to reduce time spent troubleshooting email delivery and minimize operational overhead. What should a solutions architect do?

Amazon Simple Email Service (SES) is a cost-effective, flexible, and scalable email service that allows developers to send mail from within any application. By configuring the web instance to send email through SES, the company leverages a managed service specifically designed for email delivery, reducing troubleshooting time and operational overhead. SES handles the complexities of email sending, including deliverability, bounces, and complaints, which are common issues when sending email directly from EC2 instances. Creating a separate application tier using EC2 instances for email processing, whether standalone or in an Auto Scaling group, introduces additional infrastructure to manage and doesn't inherently solve email deliverability issues; it merely offloads the sending process. Amazon Simple Notification Service (SNS) is a messaging service used for sending notifications to various endpoints, not for sending marketing or order confirmation emails directly to end-users.
