Which tray is required for a USPS Presorted Marketing Mail machinable mailing?

For a USPS Presorted Marketing Mail machinable mailing, the required tray is the Mixed AADC tray. This is essential because the Mixed AADC tray is specifically designed for handling machinable mail pieces that have been sorted to the 5-digit AADC level but may contain a mixture of mail destined for different delivery addresses.

This type of tray ensures that the USPS can efficiently process and deliver the mail by maintaining the appropriate sorting for bulk mailings while accommodating a variety of recipients. The "Mixed" designation indicates that the contents of the tray may combine mail pieces that, while all falling within the AADC category, do not belong to a single 5-digit ZIP Code or that may be directed to multiple delivery points within that region.

Utilizing the Mixed AADC tray allows for the efficient handling of large quantities of mail that are still eligible for the pricing associated with presorted marketing mail, thus optimizing the mailing process and ensuring that mail is delivered in a timely manner.
