Question
Unsubscribes from operational email without an unsubscribe link?
I just want to verify. Does Marketo add the list-unsubscribe link in the header on operational emails as well? It seems sometimes it's visible in the code on the recipient side and sometimes it is not. But I have a small number of unsubscribes popping up on operational emails that did not contain an unsubscribe link, and this is the only way I can think of that happening?
