BCC is your friend. this will hide the fact that you are misusing MIT mailing lists.
Lists to send emails to should include:
<ensemble@mit.edu> - members of the ensemble
<ensemble-dartes@mit.edu> - shakedartes and other people who were interested at some point to be on our mailing list
<town-crier@mit.edu> - a not well known ensemble list that has people who just want show publicity, and no spam about being involved in shows.
<mtg-social@mit.edu>
<gsp-cast@mit.edu>
<gsp-prod@mit <savoyards-discuss@mit.edu>
<dramashop@mit.edu>
<mitcp@mit.edu>
