What is the max API rate limit for the SES Sendmail / SendRawEmail Endpoints?

The Amazon SES (Simple Email Service) API rate limits for the SendEmail and SendRawEmail endpoints are not explicitly stated in the official documentation. Unlike other SES API actions which are throttled at one request per second, these specific endpoints have a different treatment.

The SendEmail and SendRawEmail endpoints are subject to your account's sending quota, which includes both a daily sending limit and a maximum sending rate (emails per second). These limits are designed to regulate the volume and speed of outgoing emails to maintain a good reputation with email providers and prevent potential flagging of suspicious activity.

The actual maximum rate at which you can call these endpoints depends on your account's specific sending quota, which can vary based on factors such as your account status and history with AWS. New SES users typically start with lower quotas that can be increased over time or upon request.

If you need to know your specific sending rate limit, you should check your AWS SES console or contact AWS support for the most accurate and up-to-date information for your account. Keep in mind that these limits can be adjusted based on your needs and usage patterns, subject to AWS approval.

It's important to note that while there isn't a fixed API rate limit for these endpoints, you should design your application to respect the sending quotas assigned to your account to ensure smooth operation and maintain good standing with the service.
