Push notifications send alerts straight to the phones of people who have your organization's Rock Mobile app, so a time-sensitive message lands even when no one is checking email. ImportantPrerequisite You need a published Rock Mobile app. Push is configured on the mobile application itself at Admin Tools > Mobile Applications, and the setup is covered in the Push Notifications article of the Mobile Docs. Once push is set up, send a one-time blast from Communications > Mass Push Notification. See Sending Mass Push Notifications for details.
