Which feature allows users to receive updates via email regarding changes in Smartsheet?

The feature that allows users to receive updates via email regarding changes in Smartsheet is Alerts and Reminders. This functionality enables users to set up notifications that trigger when specific changes occur, such as when a row is added, modified, or deleted. Users can customize these alerts to receive timely updates directly in their email, ensuring they stay informed about critical changes without having to constantly check the sheet.

Other options serve different purposes: Shared Links are used for sharing sheets or reports with others, Dashboard insights provide a visual representation of data consolidated from multiple sheets, and Calendar integration connects Smartsheet with external calendar applications but does not specifically focus on sending updates about changes within Smartsheet itself. Therefore, the capability for users to receive change notifications via email is distinctly offered by Alerts and Reminders.
