error was caused by the following line of code... _superuser = User.objects.filter(is_superuser=True).values_list('email').first()

I changed this to _superuser = User.objects.filter(is_superuser=True).first() _superuser = _superuser.email

_msg.send was expecting the email as the first parameter, andnot the whole shooting match as I did originally.
