Is it possible to change the domain level of a cookie set by clicking on a link from a Campaign Standard email. Right now the cookie is set on a sub domain, I want to set it on a top level instead.
I would like to do this without sending out mails on the top level domain.
Did you set up a branding configuration with your desire subdomain?
also, raise a ticket adobe support for whitelisting subdomain, if it's not yet done then.
