Understanding the Error

The error message typically occurs when the domain for the iframe src is not valid or is not allowed to be iframed. This could be due to the external website’s configuration or the Marketing Cloud Next settings.

To resolve this issue, it is essential to understand the platform-level cause of the error.

The root cause of the error is often the external website’s security policy, which may not allow iframing from other domains. Additionally, Marketing Cloud Next has its own security settings that may restrict iframing.

Step-by-Step Solution

To embed an external URL within an iframe on a Marketing Cloud Next landing page, follow these steps:

First, ensure the external URL is added to the Trusted Sites list in the Landing Page Builder. Then, verify that the external website allows iframing by testing it on another website.

If the issue persists, check the external website’s security policy and ensure it is not blocking iframing from Marketing Cloud Next.

Next, review the Marketing Cloud Next security settings to ensure they are not restricting iframing.
