When trying to inform all of our customers about important information while using the mass customer contact, the customer must opt to get an email, robo call or sms text. Otherwise we are unable to inform all customers of important issues such as, leaks, road closures, interruption of services or time sensitive items. My suggestion is that a mandatory button is added to the information messages option, to be able to reach all of our customers when time sensitive issues that will affect them arise.
