Is it possible to have Data Loss Prevention(DLP) execute a policy response rule based on the response rules of another policy? For example, if I have an email message that triggers two different policies and both of those policies have Email Notification response rules attached to them, can I have only one of the policies send an Email Notification in order to avoid sending multiple Email Notifications for the same detected message?

There is currently no way in DLP to base the execution of a response rule off of a response rule in another policy. There is no conditional logic that operates from policy to policy. However, between different response rule types, there is a pre-established execution priority order as per About response rule action execution priority.
