Administrators configure different types of behaviors for their users' notifications in Anaplan, from the tenant level to the user level.
The Notifications option of the Administration panel gives you control over some types of notifications the system sends to users, as well as the ability to override notifications at a tenant level.
Under Users and roles, configure notifications for users when these are added or removed from a workspace.
Under 3rd party notifications, configure this to set whether users receive notifications in Slack, by email, or on mobile. This setting is applied at the tenant level and overrides any user-level settings created by users. This does not cover essential notifications, which allow users to reset passwords, for example.
