I found this thread because just today I submitted a request ticket to unblock email in my AWS account and it was rejected for similarly vague reasons below. In my case I’m using an EC2 instance attached to an Elastic IP.
Thank you for submitting your request to have the email sending limit removed from your account and/or for an rDNS update.
This account, or those linked to it, have been identified as having at least one of the following:
- A history of violations of the AWS Acceptable Use Policy
- A history of being not consistently in good standing with billing
- Not provided a valid/clear use case to warrant sending mail from EC2
Unfortunately, we are unable to process your request at this time, please consider looking into the Simple Email Service. Cloud Email Service — Amazon Simple Email Service (SES) — Amazon Web Services

I’ve had this AWS account for nearly 10 years, but as far as I know I’ve never had any violations or payment issues on this account. So I truly have no idea why it was rejected since that canned response could mean anything.
I’ve replied to the request asking for more details, I will update when I hear back.
