Bulk Mailing

A bulk mailing consists of 200 or more pieces of mail. 

  • Each piece must be exactly the same size, print content, paper, etc. 
  • The actual count must be indicated on the blue slip.  
  • The mail must be in zip code order, lowest to highest, front to back. 
  • If the mail is in envelopes, they must be sealed. 
  • If they are folded, they should have one or two tabs securing the ends.
  • The indicia (bulk stamp) must be printed or stamped in the upper right hand corner of the mail piece before it reaches the mailroom.  Call General Services at (313) 593-5481 to obtain the correct wording for the indicia or to borrow a stamp.
  • The mail must be official University business and not sponsored by an outside group, organization or association.
