Adding delivery channels in AWS User Notifications
You can add delivery channels for both user-configured notifications and AWS managed notifications from the User Notifications console to have your notifications sent to other locations.
Note
Emails you receive from User Notifications are sent from the domain @aws.com. The prefix of the emails you receive reflect the AWS service 
   sending the communication. For example, notifications from AWS Health are sent from the email health@aws.com and Amazon CloudWatch notifications 
   are sent from a cloudwatch@aws.com email address.
