Preview is a feature that allows you to see your campaign without having the campaign deployed on your website, but not all web pages allow this. If it is not working with your website, here are some troubleshooting steps to try.
If you get an error such as the ones below, it may be that your website is blocking proxy or cross-domain requests. This would be a configuration that was made by the IT team in charge of the webpage, perhaps as some sort of connection timeout or DoS attack prevention measures. You may need to work with your IT team to have the proxy request enabled.
In cases where the preview option doesn't work due to website proxy or cross-domain restrictions, and you want to see what you campaign looks like live on your website without customers seeing it, we recommend using a Sandbox segment. Sandboxing allows you to match a segment and see the campaign live by targeting a specific term added into the URL. Since leads won't randomly guess the value and alter the URL, it's safe to test on a live site. Here's how you do it.
In order to see the campaign again or changes made, you will need to clear browser cookies.
