I unsubscribed from a company’s mailing list and then they added me to a new “unsubscribers” list and spammed me again. I then unsubscribed from that list and was added to another “unsubscriber” list. At least this new unsubscriber list was labelled “new”. That makes it so much better. /s*
Just mark those as spam if you are using any big email providers. Causes much more headache for them and you don’t need to play their find the correct unsubscribe button games
