  Use the Bcc header field:

    To: your-address-here
    Bcc: member1, member2, member3, ..., membern

  The recipients see this:

    To: your-address-here

    ------- Blind-Carbon-Copy

    Content of message, with headers

  If you don't want the "Blind-Carbon-Copy" message, use the Dcc
  field, but this is discouraged in true blind carbon copies since the
  warning may prevent the recipient from embarrassing someone
  inadvertently. Read the warning in (see "What is the Dcc header?").
