Several people, including myself, have been commenting that they are seeing new Gmail warnings today. This doesn’t seem to be consistent across all Gmail accounts or senders, and doesn’t seem to be impacting Google Workspace accounts. The error links to a Google support document about reporting spam and List-Unsubscribe details. This seems to be a false positive alert from Gmail and according to their status pages they are working to fix the error as soon as possible.
An update from Google reads as follows:
Jul 7, 2022 6:31 p.m. UTC
We are experiencing an issue with Gmail wherein emails delivered between 2022-07-06 20:36 PDT – 2022-07-07 00:08 PDT has a redundant banner notification in the users’ inbox.
Impact is limited to Gmail consumers and not to Enterprise customers. New emails delivered post the impact time will not have this incorrect banner.
