To our chagrin, we have confirmed that even with workspaces activated, we get only one branding domain for all pURLs in all e-mails. This seems to fly in the face of the claim that workspaces and lead partitions can be used to manage several brands.
If we were Gap, for example, we'd need a separate instance just to get links to click.oldnavy.com. I have no choice but to accept this technical reality, but at the same time I'm kind of dumbfounded about the inability to manage sister brands/bridge lines/etc. in the same place and yet segregrate them at send time.
Of course it helps the service's bottom line to get 1MM leads in each of 3 different instances. But, suspending my cynicism for the moment, somehow I don't think that's the underlying reason it isn't possible. But can some users explain how they changed or formed their marketing philosophy so that it was okay that only the parent brand appears in e-mails?
