To use the BCC (Blind Carbon Copy) feature, in a new message window,
either click View | All Headers and type in the addresses separated by a;
Or: Click the To button. You will see your list of contacts and the choice
of putting them in the To, CC, or BCC field. Click on an address, then
click BCC to add it. Repeat for all the contacts you want. (Note: Most
ISPs have limits as to how many e-mails you can send a one time. 25 is
common, but it varies).
Put your own address in the To box. This is the only address/name that any
recipient will see. If you leave the To field blank, some people may not
receive the e-mail due to message rules they have set up, or restrictions
set by their ISP.
You can also make an entry in the Address Book using your e-mail address,
but putting something like Mailing List in the display field.
