I don't get how this works... If Joe User's receiving email server doesn't do encryption then how the heck is the email encrypted end to end? The graphic on the site says "If receiving server is unable to handle secure email, a notification is sent to view on secure web app." so what a link is sent? that link is not encrypted thus anyone can click it and then anyone can open the email on the "secure site"... There is a massive hole in this whole setup, too much marketing....
