Some of the best-reviewed email management database solutions as of 2015 are Campaign Monitor, InfusionSoft, Zoho and Insightly. These packages are designed for managing email information for email campaigns and marketing purposes for businesses of all sizes. Many also provide ways to manage contact information for other methods of electronic communication, such as Twitter and chat programs.
While older email databases were often designed to track messages and contact information for email accounts only, the prevalence of alternate electronic communication methods has lead to the concept of email databases expanding into more comprehensive customer relations management databases. Despite the name, these tools can be useful for anyone who needs to manage contact information and messages for a large number of individuals.
In addition to storing contact information, most customer relations management databases also allow users to segment their contacts into subgroups for targeted email campaigns or data analysis, as well as specifying preferred alternate forms of contact for specific individuals. Though many of the best email database packages are proprietary software due to their business orientation and additional features, some databases such as Zoho are free to use, and many proprietary databases offer free tiers of service with limited features.
