A suspicious email blast from Synchrony Bank worried customers on Monday about possible fraudulent activity. One email said a trial deposit had been made to an Amazon credit-builder account. Another email said action was required on an application.

Three emails or messages were sent within an hour. Many people reported about the issue on social media.

Have @Amazon and @synchrony been hacked?? Any updates on this nonsense before I go full lock down? Not like I have anything else to do today, at all….. pic.twitter.com/kFejkDr4hU

Synchrony told Business Insider and some customers that it was all in error. “Synchrony is aware of an unplanned notification that was distributed in error to some consumers. The email sent in error did not include any customer data or personal information. We are currently investigating the notification and the root cause.”

Amazon also said it was aware of the issue.

“Amazon is aware of a notification that was distributed by Synchrony in error to some customers,” an Amazon spokesperson told Business Insider. “They are investigating the root cause. Additional inquiries can be sent to Synchrony.”
