from tec side there is not really a difference between marketing and other mails, dealing with their domains might never end , but you can always use your own a reject list on smtp level cause why should you do expensive content filter to known not wanted domains. At the end ,at a server with many different users you will see that some marketing is really wanted by some users, but others like to see it so best way for this are users own white/blacklists after you filtered the most bad things global.
