By default, new email subscribers are subscribed to notifications for all components.
Subscribers can choose the specific components/containers that they want to receive notifications for. All new subscribers are sent a unique link to manage their subscription preferences. This link is also included at the bottom of every status notification.
You can also manually manage the subscribers for your status page by logging into the dashboard and selecting the Notifications tab. Click the Manage Subscriber button for a subscriber and then check/uncheck the appropriate components.
