Enterprise can help you quickly and easily verify that the links and images in your mailing are retrieving images and web pages successfully. It should be noted that this feature should not replace manual testing of links and images. Below is a list of some of the common responses that you might see when checking your links and images. Unknown status (yellow) could indicate a temporary problem and should be manually verified before sending your mailing.


Status Response Details

OK HTTP status 200. Content was returned successfully. Because the content that was returned might not be the content you expected, however, it is advisable to check all links and images manually.

Found/MovedPermanently HTTP status 302 or 301. While it is common for web pages to redirect the browser to other web pages or websites, such redirects can occasionally result in the browser being caught in an endless loop. The Found or MovedPermanently status indicates that the browser has been redirected more than 20 successive times, which most likely indicates an endless loop.
