Need a file merger just like A.F.7 ([url removed, login to view]) - The only difference is that I need it to remove duplicates, and add another function:
It must have another option to upload a file of emails(.txt) that we do not want to be included in the merge.
For instance, we have 20 files of emails that we want combined (100k emails). We have a list of emails that we would like to remove from that list (about 5k-10k emails) and remove any duplicates that are there. and save it to a .txt file name that I choose. Should be saved as a list (1 email per line).
