Direct mail printing refers to the process of creating and producing physical promotional materials for use in direct mail campaigns. This can include printing postcards, flyers, catalogs, or letters and inserts, such as buckslips, coupons, or samples. Direct mail printing can be done in-house or by a commercial printer, and the choice of printing method will depend on the volume and complexity of the materials being printed. Direct mail printing often includes personalization and variable data printing, allowing marketers to create unique and relevant materials for each recipient based on demographic, geographic, or psychographic information. The quality and appearance of direct mail printing can significantly impact the success of a direct mail campaign and the brand's overall image.
