The new authentication requirements that have been put in place are actually just mandating something that any genuine and professional marketer should already be doing. This includes using Domain-based Message Authentication, Reporting & Conformance, DomainKeys Identified Mail and Sender Policy Framework to validate that their messages are originating from the source as claimed. According to Gmail group product manager, Neil Kumaran, this step will help eliminate loopholes that attackers use to threaten everyone who uses email. Though it’s not a guaranteed solution to preventing spam and malicious email content, it goes a long way in making our Gmail inboxes safer and less spammy. However, there is still a threat to watch out for, called SubdoMailing, which should be considered.

While the introduction of these new security rules is akin to the icing on Gmail’s 20th birthday cake, it should be noted that they only apply to emails sent to personal Gmail account holders and not Google Workspace accounts. Anything that helps reduce email scams and spam is to be applauded.
