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, Amazon CloudWatch notifications
are sent from cloudwatch@aws.com, and aggregated notifications are sent from notifications@aws.com.
To find the email prefix for a specific service email, inspect the event through the Amazon EventBridge sandbox.
If your organization uses an email allow list, add the @aws.com domain to ensure you receive all User Notifications emails.
