Emails Not Received Despite Successful Campaign Send via AWS SES

ℹ️ Support

I’ve created a new campaign and configured it to send emails using AWS SES. While the AWS credentials (Client ID and Secret) appear to be correct and the dashboard shows “email sent successfully,” the recipients are not receiving any emails.

Upon checking the error logs, I found the following message: “Multi-curl http code 403 result Sender InvalidClientTokenId: The security token included in the request is invalid.”
Could someone help me understand what might be causing this issue? Is it related to incorrect AWS credentials, or misconfiguration within phpList?
Thanks in advance!

@Prasanna This seems to indicate that either the Access Key Id or the Secret Access Key is not correct. Check that you have copied them correctly from AWS SES and pasted into the correct fields on the phplist Settings page.
