You use BCC instead of TO when addressing the message. BCC = Blind Carbon Copy The easiest way to do this is using the Contact Sidebar in the Write window. Press F9 to turn it on when a Write window is open. Select all the contacts for the message. Hold the control key while clicking the contacts to select multiples. Then use the Add to BCC button at the bottom.
