Amazon SES might pause your SES account’s ability to send additional emails for one of the following reasons:
If the bounce rate is more than or equal to 10%. If the complaint rate is more than or equal to 0.5%. If an AWS SES account was already placed under review and the issue wasn’t corrected before end of the review period or if the AWS SES account was placed under review several times for the same issue. If the email sent from the AWS SES account has violated the AWS Service Terms.
Note: This won’t impact any other AWS services in the AWS account. However, service quota increases for any AWS service that sends outbound communications (such as Amazon SNS) may be denied until the AWS account’s ability to email sending is restored.
I would reach out to AWS Premium Support or the Technical Account Manager on the same to check if the above are not the issue OR this has happened frequently.
Unfortunately, yes. I would recommend going for a developer plan which is the cheapest option and provides basic level support & reach out to the AWS accounts and billing team and request a review using the basic plan.
