SNS has two modes: A2A and A2P. A2A is pub-sub, A2P is for sending notifications to users (via e-mail, SMS, or mobile push) CloudWatch Alerts are sent from SNS

CloudWatch Alerts are sent from SNS, and I would imagine others are as well, although some may use SES. I think SES has the same issue, as the AWS docs only mention DMARC/DKIM in the context of a custom domain.
