## About 44G Envelope
44G Envelope is a system for the secure sending and secure pickup of digital messages and office documents. The email does not carry the actual content as a regular attachment. It only carries instructions and a security code. The recipient buys nothing and registers nothing. They simply open 44genvelope.com manually, enter the code, and securely pick up the content after verification.
