Many tags do not work in preview and test emails because there is no associated contact record (hence, the “/000000” at the end of the URL).

You would need to add yourself as a contact, send yourself a “live” copy of the messages that contain the links (by adding your contact to the autoresponder or scheduling a broadcast to be sent to your contact record), and then click on the links in the "live" emails you received for you to confirm if they work or not.

Important note: Unsubscribe links do not work in broadcasts.
