How can I email a "list" without revealing details of the list?

Do you mean a distribution list of email addresses? If so, just put them in the BCC (Blind Carbon Copy) address field.





Bcc: stands for "blind carbon copy." This is similar to the Cc: feature, except that Bcc: recipients are invisible to all the other recipients of the message (including other Bcc: recipients).





For example, if you send a message To: johndoe@yahoo.com and Bcc: janedoe@yahoo.com, then johndoe sees himself as the message's only recipient. Janedoe, on the other hand, is "in the know"鈥攕he can see that you sent the message To: johndoe, and that you blind-copied her.





To add an entry in the Bcc: field, click the "Show BCC" link above the "To:" field.

put your email in the "TO" box and the list name in the "BCC" (Blind Carbon Copy) box. You should get a copy saying who it went to, the list should just all get copies without everyone's names.
