Sending an email message is not like sending a sealed envelope through the postal service. communications on paper are far less likely to be read by someone the message is not intended for. this is not true with email, which can be forwarded by the recipient to whomever he chooses. the challenge for any business person is to think clearly about the content of the email message he is about to send and the unintended consequences of the information ending up in the wrong in-box.
