Direct advertising refers to a form of marketing communication where companies directly reach out to potential customers through various channels, such as mail, email, phone calls, or text messages. This type of advertising allows businesses to target specific individuals or groups with personalized messages, promoting their products or services in a direct and immediate manner. Unlike traditional advertising, which relies on mass media to reach a wide audience, direct advertising aims to establish a direct and personal connection with consumers, often resulting in a higher response rate and increased sales.
