A method to provide a digital notification and response to groups of users comprising storing user contact data for at least one group of users, user selected priority information, and user selected grouping information in a dynamic information database, and using an administrator interface to form at least one message. An administrator initiates transmission of the message simultaneously to a first group of user contact devices for all users in the at least one group of users, then simultaneously to a second group of user contact devices, using the user selected priority information and transmitting the message through at least two industry standard gateways simultaneously. The administrator interface is used to ensure each user is contacted on the first group of user contact devices before the second group of user contact devices using the user selected priority information.
