Postal Letter

How do I send an e-mail to a group of people so individuals in the group won't see each others address's?

I have a e-mail contact group of 53 people that I need to send the same e-mail to. How do I hide their addresses so they all won't see each others e-mail? It's basically a privacy concern. I use Windows Mail.

1. Put all the address in the BCC feild. This is a blind carbon copy. They'll see your address and theirs, and that's it.
2. BCC everyone.
