Emails getting Images being hidden -- Our logo/Signature file

mfoley — Mon, 02 Feb 2026 19:30:00 GMT

We recently started noticing this error when email (Google Workspace) internally on our email lists, "Images in this message are hidden. This message appears suspicious. Don't show the images unless you trust the sender and the message."

The only Image in the email is our signature file, the school logo hosted on our website. (Set with GAM)

How do I prevent this from appearing suspicious? it appears to have worked fine up until a few weeks ago.

DMARC Set to Reject, DKIM set, SPF set

Check your setting here. It should be ON (I mean keep it ON).

Most likely Gmail considers your linked image to be hosted externally.

However, my strongest recommendation is to avoid images in signatures altogether. They're such a waste of both bandwidth and storage.

But think of the marketing people!
