A detail person is a salesperson working as a manufacturer's representative who visits the manufacturer's customers to take care of details and promote goodwill.
House-to-house selling, often referred to as door-to-door selling, is a direct sales technique where sales representatives visit potential customers at their homes, either with or without an appointment, to pitch products or services.
Personal Selling involves the delivery of a uniquely tailored message to potential customers (prospects) by a seller, usually through face-to-face communication, personal correspondence, or personal telephone conversations. Unlike advertising, a personal sales message can be specifically targeted to individual prospects and can be easily adapted if the desired behavior is not achieved.
A promotion mix is a blend of various promotional methods aimed at achieving marketing objectives, including advertising, personal selling, publicity, and sales promotion.
Sales promotion encompasses activities, materials, devices, and techniques used to supplement advertising and marketing efforts, coordinating them with personal selling activities to boost product or service sales.
