Mail: MDI provides several levels of service when it
comes to mailing through the USPS for delivery. In normal delivery of
smaller quantities, your mailing to the Bulk Mail Centers using the USPS's
trucking and distribution is sufficient. However, in larger mail
quantities with high density in certain markets, destination entry and
customized logistical trucking of your mail, can not only provide more
predictable in-home delivery, it can save you thousands of dollars in
postal discounts.
