Since governments usually deal with large lists of email recipients, the need for a mass email software like Campaign Enterprise is extremely useful in getting out various types of material.  Government agencies also have strict requirements with security and privacy.  Since Campaign Enterprise is an in-house software, the agency can preserve the integrity of their security by connecting to their own internal databases. They do not have to send their lists out to an email sending service. Campaign Enterprise has been used from local governments to nation-wide federal agencies in the United States and other countries, always taking secure measures with reliability.
