Built by CMI Software

MuniMessage is part of CMI's evolving government software portfolio.

MuniMessage is a new CMI Software product for government and public-safety teams. It is designed to operate as a standalone secure communications platform, while also fitting into CMI's broader government software portfolio.

As the CMI Justice platform evolves, MuniMessage is planned to integrate with the newest generation of Justice products, giving agencies a path to connect secure communications with the systems they already use.
