Once Envelope Manager has sorted your mail, printed the reports, printed your tray or sack labels, and printed your mailpieces, the rest of the work is up to you. Your Post Office can tell you more about how and where they want to receive your mail. They can also provide you with the trays or sacks you need. Here are a few general reminders about what you need to do:

Letters and Postcards
If you followed the instructions, your mailpieces printed out in the order they go in the trays. Lift them from the printer to the trays in that order. The second column in your traying report lists the tray size--”1” indicates a one-foot cardboard tray, “2” marks the more common two-foot cardboard trays. If you printed tray separators, they mark the beginning of each new tray--but do not put them in the trays.

• Don’t worry if some of your one-foot trays have very few pieces in them. That is normal for some SCF trays and some carrier route trays.
• You will need to put cardboard sleeves, and probably plastic straps too, on your trays. Ask your Post Office for supplies and instructions.
• Envelope Manager printed tray labels for you. Put them in the plastic holders on the end of each tray.
• All postcard-sized pieces must be rubber-banded into packages.
• Tilt your tray at a 45% angle. If the pieces do not fill at least 3/4 of the tray’s length, the tray is officially "less-than-full" and you need to package them with rubber bands.
• 5-digit carrier route automation trays need separator cards between carrier routes. Line of Travel 5-digit trays need each carrier route rubber-banded into packages.

If you followed the instructions, your mailpieces printed out in the order they get packaged, with the packages in the order they go into trays/sacks. Start a new package every time you see an Optional Endorsement Line like “*** 5-Digit 49441” or “*** MIXED AADC 270” above the address. If you used the tray and piece number Optional Endorsement Lines too, numbers like “T1/P1”, “T1/P2”, “T1/P3”, etc., will help you keep track of which tray/sack and piece you’re on. If you printed sack separators, they mark the beginning of each new sack--but do not put them in the sacks.

If you did not use the Optional Endorsement Lines, you need stickers on the front of each package to identify its type. One of the reports Envelope Manager printed for you lists the packages and their contents by type. Note that multiple types of packages (5-Digit, 3-Digit, ADC, and Mixed ADC) can often go in the same sack/tray.

Sacks and trays need tray or sack labels. Envelope Manager printed them for you earlier. You may also want to see our list of what you need to bring to the post office.
