How does Marketing Cloud handle subscribers when they click the ESP system generated
This message is from a mailing list -- Unsubscribe button at the top of some of our emails?
I was looking through the documentation but can't seem to find it.
We have a custom preference center and I most certainly imagine that that link doesn't send a programatic command to update the data extension. My assumption is that it acts like a Global Unsubscribe at the parent level, but without digging into the data, I can't be sure.
**Basis of the question is really how to tie back subscribers that 'click' the link their mail client serves up when it says that 'this email is from a mailing list' -- to our Custom Preference Center data extension
