Gmail is making it very clear for its users when you’ve been sent a sketchy link. If you use Gmail on the web or on Android. You’ll see a question mark in place of the sender’s profile photo if the message wasn’t authenticated by either the Sender Policy Framework (SPF) or DKIM). Those who check Gmail on the web will see a familiar warning message similar to Google’s Safe Browsing protection tool that’ll let you know you might be clicking a link that has malware or uses phishing to get your personal information. Google is quick to emphasize that of course not all affected emails could be dangerous. But it is definitely better to be on high alert in situations like this.
