One way many of our customers use text alerts are for emergencies. This is a case where we would rather see text alerts not be used.
Text alerts are a great way to let people know quickly about extreme emergencies: Fires, intruders, weather emergencies, etc. It is also great for things a little less severe and serious. Server outages, traffic jams, etc.
What kind of plan do you have in place when these types of things arise? Hopefully none of these things happen to you, but in case they do, make sure you are prepared!
