The ATLAS Institute uses email lists, built based on official rosters, to communicate with faculty, staff and students. If you are not receiving messages that you know were sent to a group to which you belong, email atlascommunications@colorado.edu. To post to a list, you must be subscribed to that list, and your message must come directly from the listed account. (Sending from another account using "send-as" functionality that matches the subscribed email address doesn't work.)
