Direct mail is best suited to reinforce messages about price, trust, and relationships with customers. It adds intimacy to a brand's communications plan, making customers feel more connected than they would through impersonal push media alone. Advertising mail remains the most effective push channel for activating purchases. When direct mail is added to email campaigns, it drives more website visits, purchases, and coupon redemptions compared to email only campaigns. Campaigns that include direct mail are more effective overall according to research.
