Direct mail refers to a marketing strategy that involves sending promotional materials, such as letters, postcards, or brochures, directly to potential customers through the mail. This form of advertising allows businesses to target specific demographics and geographic areas, making it a highly personalized and targeted approach. Unlike other forms of marketing, direct mail allows for a tangible and physical connection with the recipient, making it a powerful tool for building brand awareness and driving sales. With the rise of digital marketing, direct mail has evolved to incorporate technology, such as personalized URLs and QR codes, to further enhance its effectiveness.
