Government Messaging Capabilities

Government organizations can message citizens on the free app, not connected to their organization as members, at the city or county level. Each message sent to a PubSafe user not a member of the organization will incur a per message charge. The fee is displayed before the message is sent and is considerably cheaper than SMS. There are not fees to message members of your organization.
