Which form of advertising involves sending postcards and flyers to potential customers?

Direct mail advertising is characterized by sending physical marketing materials, such as postcards and flyers, directly to potential customers' mailboxes. This form of advertising allows businesses to reach a targeted audience based on demographics, location, and purchasing behavior. It fosters a personal touch, as recipients receive tangible materials that can lead to higher engagement rates compared to digital methods.

With direct mail, businesses can craft specific messages suited for different audience segments and track response rates effectively, making it a valuable strategy for driving local or immediate business. The possibility of including promotional offers or coupons on the flyers also adds to its effectiveness in attracting new customers.

In contrast, the other advertising methods listed involve different mediums—such as digital platforms, broadcast, or social media networks—each with unique engagement strategies and target audiences, making them distinct from the physical approach of direct mail advertising.
