Emergency Management

Emergency Notifications

Emergency Notifications are sent via several methods to warn the University community of imminent threats or disruptions to campus services, such as class cancellations. Alerts are only sent when there is a potential threat to safety or a major disruption to campus services, and for monthly tests.

Students, faculty and staff are encouraged to register their mobile phone number to receive texts. Additional email addresses and phone numbers can be added following the instructions in the Account Management section.

Alerting Methods


All email addresses automatically receive CU Alerts. You can easily add additional or family members’ email addresses through your account by following the instructions in the Account Management section.
