So we did some SPAM tests on the emails we're sending, and SpamAssassin gives the HTML_IMAGE_ONLY_12 label to this email.

The description says This may indicate a message using an image instead of words in order to sidestep text-based filtering.
But the email has no images at all.

It is indeed a bit short, but as it has no images, that shouldn't make it suspicious of being SPAM.

Here's the email's content:

Thank you for your interest in following me.
Please confirm that you would like to receive email updates by clicking the link below.

Yes, I want to follow John Doe

Thank you
John Doe

So what should I do to avoid this?
Just include filler text?

Ahh SPAM_ASSASSIN. I have used that for years with success. I understand what you are saying, however SPAM_ASSASSIN is not perfect. Sometimes false readings will popup if triggered. The only way I see this affecting you is that the HTML_IMAGE_ONLY_12 score is making the email marked as SPAM. You can either lower the score, or if there is no affect, ignore it. Also, look at the size of the email. If it is just text, it should be 1-2Kb. If it is larger, then the email author has snuck an image into the email. Hope this helps.

Sometimes there are hidden image beacons embedded in emails so they can be tracked. SendGrid, for example, does this, as most email services do.
