What is Zero Download Messenger (ZDM)?

Encryption > Voltage
Zero Download Messenger (ZDM) is an interface that allows subscribers to initiate secure e-mail without the need to install CipherPost software. It also allows your recipients to read your secure e-mail and reply securely. ZDM is not a Web mail system and does not store/archive any secure e-mail. Messages will only reside in your recipients inbox. ZDM requires that you log in each time you access the system and the session will timeout after a short amount of time for security purposes.

If you already have a CipherPost account you can access the ZDM at

Tip: If you initiate secure e-mail, click the check box to send a copy of the message to yourself for your own records.
