We have a communication going out to our employees that links to an internal page which requires a login or SSO. The information appended by Marketo is breaking the link when users click. A long time ago we ran into the same problem, and I added a tag to the link formatting that kept the link as is instead of making it track-able and appending information. I realize that I won't be able to report on the engagement, but that's not a big deal for this situation - we just need to get the email out. I can't for the life of me remember what that tag was.
Does anyone know what that tag is? I've searched on the community, but searching for anything with "tracking" brings up a whole mess of results.
