At whatever point conceivable, Google email safeguards your info by using Transport Layer Security (TLS) to automatically encrypt mails you send or receive.
Transport Layer Security doesn’t work with messages from some email services.
Check emails you’ve received
- On your PC, Log in to Gmail.
- Open emails.
In the top left corner of the email, under the sender’s name, check for No TLS.
If you are seeing this icon, the emails you’ve received might not be encrypted. The sender can find out more by contacting their mail service provider.
Check emails you’re sending
- On your pc, log in to Gmail.
- In the top left corner, click Compose email.
- In the “To,” “Cc,” or “Bcc” text field, type recipient’s email address.
- On the right of the receiver’s email address, look for No TLS.
If you are seeing this icon, the emails you’re about to send might not be encrypted. Don’t send confidential material in it, like tax forms or any contracts, to that email address.
