Amaze Pro supports embedding content in an iFrame, including custom forms from Omnisend . To include an Omnisend HTML form in your project, do the following.
From Omnisend:
1. Follow these directions to get the custom iFrame code from your Omnisend account: Custom HTML Signup Form

You will need the active URL for the form you wish to embed
2. Modify the iFrame code block with your active form URL:
- <iframe name="iframe1" id="iframe1" src="https://YOUR_FORMS_ACVITE_URL.html" frameborder="0" border="0" cellspacing="0" style="overflow:scroll;width: 100%;height:100%;border-width: 0px; height: 700px" scrolling="no"></iframe>
In Amaze Pro
