Outlook email addressing

I am looking for a way to send one copy of an newsletter via email to multiple recipients and at the same time hide all recipients' addresses from each other.
I want to make it so everyone will see the mail was being mailed by me, and the To: field will only show their own individual addresses.

Is there a way to do this other than with specific software?
If not, any recommendations as to what should I use?

Thanks

 

Click on the CC for carbon copy and then select BCC for blind carbon copy. Put all your recipients in the BCC and in the main field send it to yourself.

 

Thanks for that, but BCC doesn't do what I want, as I require each recipient to have their own address shown as a recipient.
I now think I can achieve this via a mailing list with my ISP.
