Civi is a great platform and I started to use with the first action to organize some old contacts. I could import them fine and I see them in the system. The problem is that we are doing some cross-checking for the accounts' current validity and at some point we need to delete some of them but based on a list of items, let's say emails that should be inputted somehow. So the question is: is there an option like that? An input area like the "import contacts" where we can upload a file (maybe csv or text) with the emails to delete, then the script would just remove the contacts found.
Thank you very much!
