Bit stuck here - a customer emailed this morning to say our unsubscribe link is not working, so I checked the email sent and they were correct, our marketo unsubscribe landing page just lands on a can't be reached error.
Our IT manager has checked through the CNAME settings and everything is set up correctly.
We don't have many landing pages set up but it looks like it affects all of them - our subscribe page doesn't work either.
