Sending EMail messages costs the time charges for the time of transmission of the message and the time that all your addressees take to receive the message. Therefore, it would cost $1.11* to send and receive a five page message to four people, but it costs $43.00* to send the same message to the same four people by Express Mail. Thus, when you have multiple addressees, it's cheaper to send your message via EMail.
