try bcc
for blind carbon copy

Put your own e-mail in the “TO” field and then “BCC” (blind carbon copy) everyone else. All the people on your list will get the e-mail, but it will look like you only sent it to yourself.

if you put all the email addresses into a group, that should do it.

or, enter all the addresses into the BCC field.

Use bcc:
It’s called blind carbon copy. In your address line there should be a place for addresses, cc: and bcc:. What this will do is send the same email to all those listed, but the only email listed for the reciever is yours and theirs. Using cc: does the same thing, only sends the emails of the other recipients as well.

Sometimes it’s nice to have the list of people if you have the same friends so you don’t send them the same thing that you just received.

In the context of e-mail, blind carbon copy, abbreviated BCC, refers to the practice of sending a message to multiple recipients in such a way that what they receive does not contain the complete list of recipients
When sending an e-mail to multiple recipients, you can hide their e-mail addresses from each other. This is a sensible anti-spam precaution because it avoids making a long list of e-mail addresses available to all the recipients (which is what happens if you put everyone’s address in the To: or CC: fields). For this reason, it often makes sense to use the BCC: field for mailing lists. Some viruses also harvest e-mail addresses from users’ cache folder or addressbook, and large CC lists may further the propagation of unwanted viruses, giving another reason to use BCC.

I don’t think i’s possible to make an address list in Yahoo mail such that it does not show the members of the list to the recipents. However, what you can do is start a Yahoo group (http://groups.yahoo.com/) of your own and you will have a group email address.You can then add the email addresses to the group and when you send out an email to the group email, it goes to all the members but all they see in the “TO” field is the group email address and not individual email addresses. Google also offers the same service for free at. Another way of doing this is by creating a mailing list and adding email addresses to the list. You can try some free mailing lists like & easy) and (more features)

Just use the BCC (Blind Carbon Copy) function
