Google has begun rolling out major changes to Gmail that could leave millions of email accounts more exposed to spam and security threats.
One of the biggest changes is the shutdown of POP3 email fetching inside Gmail. From January 2026, users will no longer be able to pull emails from older third-party accounts into Gmail using POP.
Google is also ending support for Gmailify, a feature that applied Gmail’s spam filtering and inbox tools to non-Google accounts such as Yahoo, AOL, and Outlook. Many users were unaware they relied on this protection.
With Gmailify ending, emails from these legacy accounts will lose Gmail’s advanced spam and malware filtering. Google has advised users to switch to email forwarding, but this does not fully replace the lost protections.
Security experts warn the change could create new opportunities for attackers. Emails sent to older addresses may now reach Gmail inboxes with fewer checks in place.
The timing has raised concerns, as Gmail recently suffered a filtering issue that allowed spam to flood user inboxes. Google said the issue is mostly resolved, but some misclassified messages may remain.
Google has not fully explained why Gmailify is being retired. Analysts suggest rising AI processing costs may be a factor, as filtering and summarizing third-party emails consumes significant resources.
The changes mark one of Gmail’s biggest shifts in years. Users with older email accounts are urged to review their settings and consider migrating fully to Gmail to maintain stronger security.
