Add your recipients to the "bc" or "bcc" field instead of the "to" field. "Bc" means blind copy. "Bcc" means blind courtesy copy. If your email software still requires an address in the "to" field, send it to yourself as well.
Reply:if you type all the names into the BCC: line then all the recipients will not see each other.
Reply:Create duifferent mailing list contacts or send the emails out one at a time.
