Configure message domains
Message domains are used by the Advanced Messaging feature to create and initiate scenarios based on a specific event domain. For example, the default scenarios use the "Scenario" message domain to create scenarios based on the "advanced_messaging" event domain.
Advanced Messaging is a legacy feature originally developed for xMatters Premises version. With the continuous improvement and innovation available in communication plans, Advanced Messaging is being pushed aside for bigger and better things.
If you happen to still have the Advanced Messaging feature in use in your deployment, you can download the Advanced Messaging Guide from the xMatters customer support site at support.xmatters.com.
