Gmail focuses on sender/recipient

​Gmail supports Transport Layer Security encryption, which ensures that data is only exchanged when the connection is secure, and Gmail automatically encrypts your incoming and outgoing emails where possible. ​From now on, users will see whether the email service of the sender or recipient also offers TLS support.

If that is not the case, a red open padlock will appear next to that person's name. Another improvement is that Gmail will now indicate if the sender of an email cannot be verified. A question mark will then be shown in place of the photo, avatar, or company logo.

Tools for the right decision

Product manager John-Rae Grant emphasizes that not all unencrypted or unverified emails have to be dangerous. 'But it's best to be extra cautious when replying to or clicking on links in emails you are unsure about,' he writes. 'And with these updates, you get the tools to make the right decision.'

Google is clearly not resting on its laurels when it comes to security. Last week, the company announced that it is actively blocking websites that use social engineering attacks.
