Add iframe to post and Mailpoet shows code

Hi all,

We are a book review site, and other each review we like to add this code:

<style>iframe {width: 1px; min-width: 100%; } iframe.single_vertical { min-width: 100%; min-width: min-content; }</style><script src="https://cdn.jsdelivr.net/npm/iframe-resizer/js/iframeResizer.min.js"></script><iframe id="bzrwfrm_9789463234566" class="bzrwfrm single_horizontal" style="border: none;" src="https://t.bazarow.com/b/single.horizontal/9789463234566?a=65&s=78"></iframe><script>iFrameResize({ log: true }, '#bzrwfrm_9789463234566')</script>

The thing is that this code is shown in full within the mail newsletter, each day, with every review we post (trying to sell this book).

Is there a way to put this code within tags, so it will be shown as on site?

Looking forward to hearing from you…
