Thank you for your reply. The list is indeed on innerlijkefocus.nl, it is an existing list. But the subscribers on the subdomain (academie.innerlijkefocus.nl) are not added to that list. Nor any other list on innerlijkefocus.nl. When entering an existing subscribers emailadres on the subdomain, it also does not say that it already is on the list (as it normaly does). So somehow it is not connected to the list, I think.
