We encourage all departments to use only Yale University Inter-Departmental Mail envelopes for all of your campus mail needs. They ask for the information that Campus Mail requires to accurately and promptly deliver your mail.
Using the official Yale University Inter-Departmental Mail envelopes saves your department money. They are less expensive than going to an outside concern and you receive free overnight delivery of your envelopes from Yale's TR&S.
Order a supply of new envelopes by faxing a Stock Request to (43)6-4594.
