Some users get domain notification emails when they have stopped using CloudM Manage. If this is the case, please see our How do I remove CloudM Manage? page as you only receive these notifications with an active CloudM Manage installation.
If you have removed CloudM Manage, but still get "Marketing" emails or "update" emails about the state of CloudM Manage as a product, you will find an unsubscribe link at the bottom of the email which will remove you from our CloudM Manage mailing list.
You need to do both of these actions to not receive further emails from CloudM Manage.
