I have harvested over 40 lists, all deduped within themselves. However I need a software that can filter one list against another. For example, listA and listB may overlap a little bit. I want to filter listB against listA and remove all the URLs that are duplicated in listA. Is there a software or Addon that can do this? I've searched the internet and found some email list management software but they are all very expensive.
Thanks.
Thanks.
