Dialer systems allow real estate agents to make high volumes of calls to leads or to their database. A dialer is an automated telephone dialing system that runs through calling lists at a customizable pace, with features such as multiline calling, unlimited minutes, preview dialers, do-not-call list integration, text (SMS), and more. Many Customer Relationship Management systems (CRMs) include dialers now. Some companies listed below also provide call center software which helps inside sales agents and e-leads teams to not only follow up with inbound leads, but also set outbound calling goals, optimize call time, and monitor call performance.
