How to send encrypted email in Gmail

Transport Layer Security (TLS) is the standard encryption method that Google uses to protect your messages when you use a free Gmail account. TLS has a problem which is as follows: it can only work if the person to whom you send the email uses an email provider that also supports TLS. Even if several large suppliers use TLS, it's good to know that the risk is enormous in its use. Mutual TLS compatibility assumes that all sent messages sent via Gmail will be encrypted via TLS.

The interception of your message during its routing to the recipient is made difficult by TLS this is why nothing is promised to you by TLS by keeping your messages private between you and the recipient if it has reached them. The example you have is that of Google, which has the ability to see the messages associated with your account and analyze them to detect possible spam and malicious mail, but also to support features such as Smart Reply.

In case the person to whom you send an email uses a mail server not using TLS, there will be no encryption of your message and you will not even know that is why you must make a good choice judicious of what you send.

How to encrypt Gmail for business
