P.O. Box: Class and major lists

The P.O. Box system is a closed system for faculty and staff used to send messages to pre-defined lists of students and employees. It is useful if you want to send messages to

  • all students in a UD class (e.g., CISC181-010)
  • all students in a given major or minor
  • all students in a particular graduation year in a major or minor
  • pre-defined groups of faculty and employees.

You can only use P.O. Box to send messages to other University of Delaware email addresses (e.g., xxx@udel.edu, yyy@dept.udel.edu, etc.). Because it is a closed system, members of a P.O. Box list are not subject to spam messages. Attachments are stored on the P.O. box server.
