Which feature allows analysts to receive email notifications for changes in data?

The feature that facilitates analysts in receiving email notifications for changes in data is View Subscription. This feature allows users to subscribe to a specific view or dashboard in Tableau Server or Tableau Online. Once subscribed, analysts can set their preferences to receive email updates whenever the data in that view is updated or refreshed. This is particularly useful for monitoring key metrics, as users can get alerts without having to log in and check the dashboards manually.

While other options serve important functions within Tableau, they do not specifically provide the same notification system. Task Scheduler is primarily used to automate the running of tasks at specified times rather than to notify users about data changes. Data Alerts can inform users about specific performance thresholds or conditions being met within their data, but it is focused on alerting for significant changes rather than general updates. Extract Schedule involves setting up the times for data extract refreshes, but it does not directly serve the purpose of notifying users via email about these changes.
