We have a email that has a link going to a page on our website (https://apply.veteransunited.com/blah). When you click the link in the URL on a received email...sometimes the URL is apply.veteransunited.com/blah and sometimes it's go.vu.com/blah. Why is this? We do have a branded domain of go.vu.com setup for our landing pages but I was under the impression that a URL to a non-marketo landing page should not show as go.vu.com? Could someone help me understand this?
