The ideal way for Big Cartel users to add a review or testimonial page is create a new blank page. Follow the link below to find out how to do this.
Once you created the blank page give it a title like Reviews or Testimonials.
Then clicking on the HTML code button you can paste the full code from your testimonial robot email.
<script …. ></script>
Like so, into the page and save. This is just a basic example – style and layout as you see fit.
