I find them to be very helpful and very supportive. Offer value-added services. In the increasingly competitive envelope market, distributors who provide services come out on top. Consider offering clients design advice, warehousing, inventory management and more. Make sure the envelope fits.
Many envelopes contain multiple pieces.
A billing envelope may include a letter, statement and promotion. Direct mail envelopes often contain cover letters, brochures, plastic cards and return envelopes. Test samples on automatic filling equipment. In addition, ask clients whether they must fold the material they are inserting. If so, a larger envelope might be better.
