If you don’t have encryption on at least your email, you might as well send the information on a postcard for the world to see. If you don’t like the idea of the content of your email being put onto a postcard then you need to set up PGP as today’s best solution. Is it amazingly easy? No. Like anything it takes a little time to get started. Is it worth it? How do you feel when you wear a seat belt in a car versus when you don’t? PGP is a seat belt for your privacy and I love the feeling of knowing that even if I accidentally send the email to the wrong person, only my intended PGP-enabled recipient can read it, not the whole world. All lawyers, real estate agents, doctors, and such professions should honour their duty of privacy by using it immediately, or at least strongly recommending it to their clients/recipients. But don’t wait for them to do the right thing when you can start right now for free.
