Check Links & Images

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.
	BadGateway	HTTP status 502. There is a problem with an intermediate server (i.e., not the server that contains the requested content).
	ServiceUnavailable	HTTP status 503. The server is temporarily unavailable, usually due to high load or maintenance.
	Timeout	No response was received during the allowed time-out period for a request (30 seconds).
	NameResolutionfailure	Either the host name (e.g. "www") or domain name (e.g. "fishbowl.com") portion of the URL could not be identified by DNS. This usually indicates that the host/domain name is misspelled, but it could also be caused by a temporary DNS server issue.
	ConnectFailure	The server that hosts the requested content could not be contacted.
	InvalidURL	The URL is not syntactically valid.
	Unauthorized	HTTP status 401. The requested content is password-protected.
	Forbidden	HTTP status 403. Access to the requested content has been denied by the remote server, probably due to security configuration.
	NotFound	HTTP status 404. The requested content does not exist on the server.
	InternalServerError	HTTP status 500. An error has occurred on the server, probably due to application code or configuration issues.
