Failed email messages Logs from Cognito

Access logging is not supported for the default email option in Cognito. Troubleshooting email issues in Cognito depends on which email option you have chosen, see https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-email.html. For the default option, Amazon Cognito limits the number of emails it sends each day for your user pool. For information on service limits, see Quotas in Amazon Cognito.. For Amazon SES, see troubleshooting Amazon SES SMTP issues.
