Using Multiple Amazon SES Accounts
When you need to send distinctly different streams of email, you can send emails through Amazon SES using multiple AWS accounts. For example, you might send marketing emails from one account and transactional emails from another account, or you might use separate accounts to send email on behalf of different clients. When you use multiple AWS accounts to send emails through Amazon SES, keep the following in mind:
Make sure to monitor the emails you receive at the email address associated with each AWS account you are using. We send notifications about the status of your accounts, such as Amazon SES probation and suspension notices, to the email address associated with each particular AWS account. It is important to pay attention to the status of all of your accounts, because the suspension of one account puts the other accounts at risk of suspension.
If you are sending through multiple accounts, make sure that you send (and continue to send) different types of email through your different accounts. Using multiple accounts to send very similar content can be indicative of sending spam, and puts your accounts at risk of suspension.
