Amazon SES InvalidSNSConfiguration

The SNS topic configuration for notifications is invalid.

Understanding Amazon SES

Amazon Simple Email Service (SES) is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. It is a reliable, scalable, and cost-effective service for businesses of all sizes.

Recognizing the Symptom

When using Amazon SES, you might encounter the error InvalidSNSConfiguration. This error typically appears when there is an issue with the configuration of the Amazon Simple Notification Service (SNS) topic that is used for notifications.

Common Observations

Users may notice that their email sending notifications are not being delivered as expected, or they might receive an error message indicating an invalid SNS configuration.

Exploring the Issue

The InvalidSNSConfiguration error occurs when the SNS topic configuration for notifications is invalid. This can happen if the SNS topic does not have the correct permissions or if there are misconfigurations in the SNS settings.

Understanding the Error Code

This error code indicates that Amazon SES is unable to publish notifications to the specified SNS topic due to incorrect permissions or settings.

Steps to Fix the Issue

To resolve the InvalidSNSConfiguration error, follow these steps:

Step 1: Verify SNS Topic Permissions

  1. Navigate to the Amazon SNS Console.
  2. Select the SNS topic that you are using for notifications.
  3. Check the topic's access policy to ensure that it allows Amazon SES to publish messages. The policy should include permissions for the ses.amazonaws.com service.

Step 2: Check SNS Topic Configuration

  1. Ensure that the SNS topic is correctly configured to receive notifications from Amazon SES.
  2. Verify that the topic ARN (Amazon Resource Name) is correctly specified in your Amazon SES configuration.

Step 3: Update Permissions if Necessary

  1. If the permissions are incorrect, update the SNS topic policy to allow Amazon SES to publish notifications. You can use the following policy template:

{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Principal": {
"Service": "ses.amazonaws.com"
},
"Action": "SNS:Publish",
"Resource": "arn:aws:sns:region:account-id:topic-name"
}]
}

Conclusion

By ensuring that your SNS topic is correctly configured and has the appropriate permissions, you can resolve the InvalidSNSConfiguration error and ensure that your Amazon SES notifications are delivered successfully. For more detailed information, refer to the Amazon SES Developer Guide.
