Email Links not working properly

[Anonymous]

Just starting to use Marketo. When I preview an email I've created in Marketo all the links work fine but when I send a test the links aren't working correctly. They go to a marketo cname landing page. How do I fix this?

did you setup your CNAME in Admin?

Where is the link supposed to go to?

Is this a Sample Email or a live test you sent to yourself?

We are experiencing the same thing, except that the links have been working for 2 years, and now they are not.

We simply get a blank screen with the URL in the address bar:

This is a test send of a newsletter blast.
