In my direct mail, I have an unsubscribe link which should trigger unsubscription landing page, but all I get is error page defined for expected landing page.
Unsubscribe link looks like this: http://t.mail.agrarverlag.net/lp/LP66?pkey=<%= escapeUrl (context.profile.PKey)%>
I'm sure that landing page, direct mail, events and service are configured correctly and published.
Unsubscription works when tested separately, but not when triggered from direct mail.
Did I miss anything?
