A mass text alert system is a quick and reliable way for organizations to send critical information to large numbers of people in emergencies, such as natural disasters, active shooters, or environmental hazards. Any group that serves the public can benefit from an emergency communications system, including schools, local governments, police departments, healthcare facilities, religious organizations, unions, human resource departments, nonprofits, and businesses. To set up a mass text alert system, one must first grow their audience by collecting contact information through opt-in forms or texting a keyword to a phone number or short code linked to the customer relationship management (CRM) software. Then, an SMS service provider must be chosen that integrates with the CRM and other systems. A short code should be secured to handle high-volume communications and bypass filters. The message should be written in consideration of the tone and essential information needed to help community members navigate the emergency. Finally, the mass alert can be sent to the contacts who have opted into the emergency communications system, using APIs over every communication stream such as SMS, email, voice, video, WhatsApp, Facebook Messenger, and more.
