I've recently sent out a promotional mail shot. I designed a new document folder to promote the consultancy side of my design business. If anything it is useful just to have something to leave with prospective clients. I print out my own data sheets and use them as inserts. In today's digital age I still feel it is important to keep up a visual awareness through traditional print media. I feel that it is also important to keep my clients informed about what I do. In my opinion, the method of folder and differential inserts is more versatile than the plain brochure option. As I am in the business of brand development, I think it is equally important to build and promote my own brand.
