The default templates are being marked as spam?

This question is extracted from this issue.
Our emails are being tagged as spam. Here's the mail report from spam assassin:
We have another app sending email through the same SMTP server. The only error we have with FusionAuth and not with our other application is the HTML_IMAGE_ONLY_12 code, but I'm not sure of the meaning of this error.

It looks like the issue was our mail server. We are using Mailgun SMTP service for our mail sending and this offers a tracking feature.
This tracking feature adds a invisible image to the html code in order to get request for stats. If I deactivate this feature, the HTML_IMAGE_ONLY_12 error is gone and the mail are no longer marked as SPAM. We don't have any issues with our other applications because sent emails are bigger in text content.
