"CommAssure keeps a complete record of the email." -- the problem is that the email may contain confidential information. Using FedEx, you are reasonably sure that FedEx envelopes and packages aren't opened by the courier service.

And the comment "We hold the same ethical standards as other email services such as Yahoo Mail, GMail, etc." doesn't really cut it for extremely confidential messages. You can tell, for example, if FedEx opened an envelope, read the contents, and put it back.

A good point, and I understand. I tried to anticipate this concern: there is a user preference that purges message body info after the message has been sent. The relevant confirmation data remains, but the body is wiped.
