Contact Management Software helps you to organize all your contacts at one place. In the early days where computers were not in use, this was done using a telephone diary. As computers became mainstream this was achieved by a computer program. Today the contact manager takes a form of modern CRM system capable of communicating using email, phone or other channels.
Over the period these software have evolved into a full-fledged CRM system. Most of these come now with email, case management or ticketing, phone integration, reports, dashboards and security features.
