Direct marketing involves providing physical marketing materials directly to consumers to communicate information about a product or service without using internet, television, or radio advertisements. It removes the middleman from promotion. There are four key characteristics of direct marketing: 1) Using a database of customer information. 2) Addressing marketing messages directly to customers in the database. 3) Driving a specific call to action. 4) Emphasizing measurable responses and results. Types of direct marketing include face-to-face interactions, door-to-door sales, kiosk marketing, and leaflet handouts. Issues with direct marketing relate to privacy of customer data, honesty in representations, and potential customer harassment from excessive contact.
