13 Steps to Handle Delivery Status Notification Failure in AWS SES

When it comes to handling email deliveries, Amazon Web Services (AWS) Simple Email Service (SES) is a popular choice for its reliability and scalability. However, even the most robust systems can encounter delivery failures. In this article, we'll outline 13 steps to handle Delivery Status Notification (DSN) failures in AWS SES, ensuring your email communications remain effective and uninterrupted.

1. Understand DSNs

Delivery Status Notifications (DSNs) are automated messages sent by the receiving email server to inform the sender about the delivery status of an email. These notifications are crucial for monitoring and troubleshooting email delivery issues.

2. Enable DSNs in AWS SES

To receive DSNs, you must first enable them in your AWS SES configuration. This can be done through the AWS Management Console or via the AWS SDK.

3. Set Up SNS Notifications

Configure Amazon Simple Notification Service (SNS) to receive DSNs from SES. This allows you to get real-time notifications when delivery failures occur.

4. Monitor SNS Topics

Regularly monitor your SNS topics for incoming DSNs. You can set up alarms or automated responses based on the type of DSN received.

5. Analyze DSN Contents

When a DSN is received, carefully analyze its contents. Look for error codes, delivery status, and any additional information that might help you diagnose the problem.

6. Identify Common Failure Reasons

Familiarize yourself with common reasons for delivery failures, such as invalid email addresses, mailbox full, or server issues on the recipient's side.

7. Implement Retry Logic

For temporary failures, implement a retry logic that Resends emails after a certain delay. This can help overcome transient network issues or temporary server overloads.

8. Adjust Email Content and Format

Sometimes, delivery failures can be caused by email content or format issues. Ensure your emails comply with standard email practices and avoid using spam-like content.

9. Utilize Bounce and Complaint Handling

AWS SES provides bounce and complaint handling mechanisms. Use these to manage hard bounces (permanent failures) and complaints from recipients effectively.

10. Maintain a Clean Email List

Regularly clean your email list to remove invalid or inactive email addresses. This reduces the chances of delivery failures and improves the overall efficiency of your email campaigns.

11. Monitor Your Sender Reputation

Maintain a good sender reputation by following best practices for email sending. This includes avoiding spam-like behavior, honoring unsubscribe requests, and handling complaints promptly.
