# Notifications
Users will be subscribed to events in two different ways:
* Self subscription to the documents which have this feature enabled
* Massive subscription enabled by the administrator to a given role
Notifications will be displayed to the users on the top menu bar
{% hint style="info" %}
Emails sent to the user. In order to achieve this, truedat needs to be integrated with your smtp server.
{% endhint %}
## Self subscription
### Business Concepts
You will be able to subscribe to any business concept that you have access to. This will generate a notification for any changes produced in a concept, including changes in the business concept status.
### Quality Rules & Implementations
It will be possible to subscribe to a quality rule and to implementations, to receive notifications when a quality result has been generated. In the notification setup you will be able to select the frequency of the notification (immediately, hourly, daily) and for which typ of result (goal reached, over the threshold but below goal, below threshold, empty dataset or failed execution).
## Subscription by Role
Refer to the [Subscriptions ](/v8.4/administration/notifications.md)page on the administration section in which this functionality is explained in detail.
