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
Especially businesses ask for encrypted email. Google for Business commonly known as GSuite has a plethora of features. One of these encryption methods that encrypts email with user-specific keys to keep it protected during delivery is that of S / MIME. Only your readers will be able to decipher and read your mail.
You and your recipient must activate S / MIME in your G suite accounts for it to work. With this method, GSuite will automatically encrypt your emails when your account and the destination allow.

Start writing a new message;
Add your recipients to the "To" field;
Look to the right of the recipient names and you will see a lock icon indicating the level of encryption supported by your recipient's email provider. The icon will indicate that Gmail is kept at the lowest encryption status when there are multiple users with different levels of encryption;
Select the Lock to modify your S / MIME settings or to find out more about the encryption level of your recipient.
How to check the encryption of a received email
Follow these steps:
Open a message;
On an Android device, tap Show details> Show security details. On an iPhone or iPad, click Show Details;
You will see a colored lock icon indicating the level of encryption used to send a message.
Three different colors of encryption lock icons exist, including:
• Green: indicates the improved S / MIME encryption which is suitable for most sensitive information and requires that the recipient has the appropriate key to decrypt the email.
• Gray: indicates that the message is encrypted via TLS.
• Red: indicates that there is no encryption, ie the recipient's email provider does not support encryption.
