I have a raw-text list of 400 email addresses of people I want to invite to an alumni reuinion. I want to email an announcement to them all, but don't want every email address displayed to all recipients. I can create a group in address book, but it seems I would first have to manually create a contact for each person (which would be a painstaking task). What's the easiest way to accomplish what I need to do? Many thanks!
