It does this using a “small red unlocked padlock” icon, according to PC World, which you’ll see in the upper right-hand corner of the email in question. This is designed to inform you that, without the support of TLS encryption, a dedicated enough lurker could easily see the contents of the message as it’s traveling through the web.
While it’s unlikely that you’ll ever encounter one of these indicators, considering most major email providers already have TLS encryption in place, those of us with — or in contact with — less commonplace email addresses may be in for an unfortunate surprise during Gmail exchanges.
The upside, however, is that with these warnings being integrated into one of the most prevalently used email clients, other providers are more likely than ever to add better security measures — namely TLS encryption — to their own arsenals.
Secondly, Google is doubling down on spammers with a new question mark icon set to replace the profile pictures of users that the company’s algorithms fail to authenticate. With this, Google is trying to eradicate those weird emails you might see from ostensibly real domains like bankofamerica.com that actually couldn’t be further from actual bank notices.
As expected, Google admits that while not every email that comes through with one of these warnings is necessarily malicious, let them serve as reminders that without the right security, delivering sensitive information over the web could lead to cybercrime vulnerabilities that could otherwise be avoided.
Both of these new features will roll out to Gmail users on Tuesday, closely followed by Google for Work customers in the weeks following.
