Google's Gmail service experienced a significant malfunction with its email filtering systems on Saturday, January 24, 2026. Users reported that emails normally sorted into "Promotions" or "Social" tabs were instead flooding their primary inboxes. Additionally, many of these misclassified emails carried warning banners advising caution because they had not been scanned for spam.
Google acknowledged the problem, stating they were aware that some users were experiencing "misclassification of emails in their inbox and additional spam warnings." The company confirmed via its Workspace status dashboard and statements to media that its engineering teams were actively investigating and working to resolve the issue. Some users also reported delays in receiving messages, which affected services like two-factor authentication.
