Subscription-based notifications enable users to proactively subscribe to items that interest them and unsubscribe from messages that are not mandatory.

Users can also specify additional notification channels that each of their notifications can be configured to use.

Before users can manage the notifications that are sent to them, administrators must create email notifications to which users can subscribe. Administrators can also make subscription-based notifications mandatory so users cannot unsubscribe to them. Then users can subscribe or unsubscribe to the notifications, and add schedules and filters to the subscription to limit the notifications that can be received.

Notifications that administrators mark as subscribable are automatically available in user notification settings. Users are limited to one subscription per notification.
