Cold Calling Sales Development Representatives (SDRs) are the first point of contact between a company and its potential customers. Cold calling SDRs are responsible for generating new leads and appointments through outbound calls, emails, and other digital channels. The goal of a cold call is to introduce the prospect to your product or service in order to start building a relationship. In order to be successful, an SDR must be knowledgeable about their products and services, as well as understand the needs of their target market.
