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.

Thank you

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