Yes! From the edit message screen, locate the "code view" button. This will allow you to add in your own custom HTML, as well as see the HTML that is currently a part of the message.
(If you are not seeing this button, we do recommend viewing the page in a wider screen.)
Please note that when using the HTML editor in Feedback genius, certain tags could be stripped due to interactions with our WYSIWYG. You might need to adjust tags to achieve your desired results. At this time, our support team does not offer code level support.
We recommend setting messages to “Test Mode” to ensure the desired result is achieved before setting messages to active.
Additionally, when adding your own HTML, please keep in mind Amazon's Allowed HTML and CSS tags.
