Good luck trying to get the email address of millionaires and billionaires. I am sure that they have a very secure network. If you have a necessity to reach a millionaire or billionaire I would try to reach them through their work. It is probably the best way. Most individuals see their email as a very private part of them, it is a way that they can talk to anyone in the world about anything
. at all. No one ever can see what is wrote unless you are the main account holder. Therefore, an email is usually only given out to prized people in their lives.
