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 mail slip. Contact the mail department to get more blue mail slips if necessary.
• 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, the fold must be on the bottom and there must be two tabs, one inch from the edges, securing the top.
• The indicia (bulk stamp) must be printed or stamped in the upper right hand corner of each piece of mail 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.
• If you are using an outside mail service to process a bulk mailing, you must contact the mailroom two weeks prior to the mailing to obtain proper paperwork for processing.

When using an outside mail service, please contact the mailroom to obtain proper paperwork for processing at the Post Office.
