How To Send Encrypted Email?

If you have sensitive information, you can easily encrypt your email messages so that no one will be able to read your emails other than your recipients. It requires authentication to send encrypted email. If you are sending emails through public Wi-Fi networks, you should encrypt emails for security purposes. Encryption makes the content of your emails not readable for someone who is trying to intercept your messages.
