Why can't I use iFrame elements in my campaign?

An iFrame is an HTML element that contains another HTML document within it. It's often used to embed a form or a video.

Currently, it is not something that most email clients support so it might cause issues in how your campaign displays or it'll just simply not appear.

What can I do instead?

You can add a link to the content you want to display in your campaign. For example, check our guide on adding videos to emails.
