Google made encryption in Gmail a default setting in 2014 for all its users. So as long as you’re using the official Gmail App or using Google Chrome to access your Gmail account, your email is encrypted by default.

However, what if the recipient of the email is not using the Google app or Chrome? Say, for example, you are sending a sensitive mail to a friend or business associate who is using Yahoo Mail.

The default encryption clause will be voided obviously! If not the recipient can’t be able to read the email because the Yahoo Mail service won’t be able to decrypt the message.
