Notifications are the text messages (email or SMS) sent to users from PortaBilling about service and billing-related events like invoice generation, password changes, custom report execution, etc.
Notifications are organized into notification sets, where each notification has a defined template. You can edit notifications by modifying the subject lines or the text within a notification template.
Notification sets can be assigned to a user, and specific notifications within the set can be enabled or disabled for the user.
