Email Distribution Groups: Catmail

Opt-in/out, listserv-style mailing lists for small or large groups of OHIO email addresses.



  • Single address: Messages sent to the group address are delivered all members.
  • One-way or two-way: A group can be a two-way discussion forum, or it can be an announcement list that only accepts mail from specific senders.
  • Moderation: Messages can be delivered immediately, or they can be held for approval by the list moderator(s).
  • Membership management - In most cases, you can manage your own list's membership.
  • University accounts only - All members must have OHIO email addresses (@ohio.edu).

Best uses

  • Discussion groups and announcement lists when all members are OHIO email users.


  • Creation: You must be a current employee, emeriti, or a registered student organization to request a new Catmail distribution group.
