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!
