There's much more to security than misaddressed messages. Email is sent over the Internet, often in the clear, exposing it to many intermediaries, including to both business and government which use mass surveillance of email to collect data on users. Email ends up on many devices, from multiple servers to multiple endpoints (sender's and recipients laptops, phones, etc.) to backups. Email security is so hard to achieve that many security professionals have given up, and design new messaging systems such as Signal. > I am not sure if fax is more secure than E-mail However, I do agree that the difference isn't great because many fax systems, sending and receiving, utilize email anyway.
