Telemarketing
Telemarketing is the marketing of products and services over the phone and a form of marketing. This work is performed by telemarketers, telephone salespeople or also called agents. Within telemarketing a distinction can be made between outbound telemarketing (also called cold calling), the active calling out to potential customers, and inbound telemarketing, the correct handling of incoming (sales) inquiries.
Many companies choose to outsource their telemarketing activities to specialized call center agencies.
