Let’s Make Email Safer – Google
Email encryption in transit
Many email providers don’t encrypt messages while they’re in transit. When you send or receive emails with one of these providers, these messages are as open to snoopers as a postcard in the mail.
A growing number of email providers are working to change that, by encrypting messages sent to and from our services using Transport Layer Security (TLS). When an email is encrypted in transit with TLS, it makes it harder for others to read what you’re sending. The data below explains the current state of email encryption in transit.

If you mail a letter to your friend, you’re hoping that she’ll be the only person who reads it. But a lot could happen to that letter on its way from you to her, and there may be prying eyes who try to read it. It’s why we send important messages in sealed envelopes rather than on the back of postcards.
Sending and receiving email works in a similar way.
As you go about your day reading, writing, and checking messages, there’s a lot that happens to deliver your emails to their intended recipients. But when you send or receive messages with an email provider who doesn’t transmit messages via a secure connection, your emails could be open to snooping.
