How does Smartsheet handle notifications for updates?

Smartsheet primarily uses email alerts and mobile app notifications to keep users informed about updates. When changes are made to a sheet, users can set up notifications that are sent via email, or they can receive alerts through the mobile app. This system ensures that team members stay updated in real time, enhancing communication and collaboration within projects.

The other options do not align with Smartsheet's notification capabilities. For instance, phone calls and in-app notifications do not encompass the full range of how updates are communicated, as email and mobile notifications are the most common and effective methods utilized. Sending physical letters is impractical and outdated in the context of digital project management, making it an unlikely choice. Similarly, posting updates on a team calendar may not provide the same immediacy or specificity as direct notifications sent to individual users. Therefore, the best representation of how Smartsheet handles notifications is indeed through email alerts or mobile app notifications.
