Tips for Bulk Mailings


  • Mailing must have at least 200 pieces.
  • Each piece must have the Non-Profit Org. Permit #3 indicia (stamp) on it …must be pre-printed on the piece or if you have already had your mailing piece printed without the indicia. Postal Services can inkjet the idicia on your mail pieces.
  • All pieces must have UMSL’s return address on them because the Post Office will match up our permit number with the return address for authenticity purposes.
  • All pieces must have the same contents (same size and weight).
  • Sending the mailing to Postal Services in zip code order will maximize savings.
  • Sending the mailing to Postal Services already sealed will also maximize savings.
  • Address labels should be typed, no handwriting for bulk mail pieces.
  • Address labels should be applied as straight and even as possible…putting labels on skewed can make the machines not read them and thus cost more to mail.
  • Self-mailing style pieces should be tabbed to stay shut and maximize savings.Note: Use tabs or tape, not staples.
  • Postal Services will fill out Postal Form 3602 and the mailhouse will bundle the mail and put it in trays with specialized labels with zip code information on them…all you need to do is have the mailing in zip code order and sealed, if possible, and you can either put rubberbands on the mailing or just put it in a mail tub/tray for pick up.
  • Call Postal Services at x5203 to have large bulk mailings picked up.
  • If you have other questions or want more detailed instructions for bulk mailings, please feel free to contact Postal Services.
