A mail-out pack can include a brochure, but often a simple information sheet or flyer can do the job. Accompanying information, in any form, serves the purpose of providing additional material about your business.

This information can come in a variety of forms: a brochure, a flyer, recent newspaper articles, and so on. These items could be kept for some time by those who receive them, so they should be capable of standing alone from the letter and be able to be read separately. For this reason it is important that they also feature your name and contact details.
