Hey @madisonlneal
You should be able to implement this exactly the way you need it. It doesn’t matter that the contact property contains the whole URL. You would just need to replace the CTA with a clickable image (please see my previous comments in this thread about how to easily convert a CTA to a JPG) and use the contact property as the href of the link. It would look like this:
<a href=“{{contact.trial_custom_link}}”><img src=“your image url” /></a>
