A wide variety of organizations and companies employ some form of direct mail marketing. For example, you might already receive an envelope from ValPak, a direct mail company that sells space in its envelopes to a variety of local businesses offering coupons and discounts. Additionally, they entice consumers to look through these coupons by promising that $100 has been inserted into 10 random envelopes.
