Marketing documents are any written, printed, visual, or digital materials used in the sales, promotion, and distribution of a product or service. They come in many forms, like brochures, catalogs, sales letters, ads, packaging, website content, promotional videos, and more. Essentially, they help to provide potential customers with information about a company’s products and services and convince them to make a purchase. As such, it’s important that marketing documents have an engaging tone and style to capture the attention of readers and ultimately convert them into customers.
