The Problem with Mobile Alerts for Mass Notification

Why Settling for Less Isn’t an Option

The emergency mass notification industry is largely centered around sending bulk SMS text messages to mobile phones. Maybe your organization is already using this kind of tool send mass messages. It’s a necessary component of an emergency mass notification system, but by itself, it’s insufficient.1 Research done at Western Washington University shows that mobile notifications are only ~80 percent effective.2 That may sound ok, but what if you’re one of the 20 percent that didn’t receive alert? What if that alert contained critical information about an active shooter, or the need to take shelter from an approaching storm? Would your organization still think 80 percent was good enough?

Many factors contribute to preventing mobile notification from reaching 100 percent of their intended audience. Some organizations don’t have everyone’s phone numbers in the system. Mobile phones are often on silent. Other times, the phone may be in a bag, briefcase or otherwise out of sight. There are many circumstances when people are required to put away their phones, such as specific health care or classroom situations. Sometimes it’s as simple a fact as being in a building with poor cellular coverage.

Learn the Ways to Reach Everyone

Combat Ineffective Notifications

The key to achieving 100 percent reach is to supplement mobile mass notification with additional communication methods, such as in-building notifications, specifically audio and visual broadcasts to existing overhead paging or public address systems, desktop alerts, digital signage and desktop phones. Using multiple channels, i.e. in-building communications as well as mobile notifications, has the added benefit of increasing the sense of urgency perceived by the recipient.3

By combining in-building notification methods with mobile notifications, your critical alerts will be received far faster and will reach much closer to 100 percent of your desired population. Achieving the highest level of speed and reach should be the goal of any mass notification system.
