How to send encrypted emails in Gmail
If you are a free Gmail user, your mailbox is protected by Transport Layer Security (TLS). TLS works when the person you are sending mail from uses an email provider that supports TLS. Most major email service providers now use TLS, so the security risk is not great.
TLS makes it impossible for others to block messages you send. However, it does not promise to guarantee the privacy of the content of messages between you and the recipient. For example, Google can link messages to your account and scan them for spam or malicious content, and support features like Smart Reply.
If the person you're sending the message to doesn't use a mail server using TLS, the message will definitely not be encrypted. Therefore, you need to choose a smarter way to send mail.
