It is important to pretest all of your processes, equipment and procedures before producing an envelope mailing. You should pretest all envelopes regardless of manufacturer recommendations for compatibility with automated insertion equipment, printing presses, printing inks, design concepts, envelope contents load and postage costs. Checking with your local post office by presenting an accurate mock-up of your final project will help to determine compatibility and postage costs and is a great way to ensure that you do not receive an unpleasant surprise when mailing your project.

By pre-testing and planning you will help yourself avoid problems and errors which may be revealed during your investigations. We recommend that you also plan for spoilage and errors by purchasing 10% to 15% more envelopes than your project requires.
