I need a program to scrub multiple email lists I have on texts documents. I have multiple lists that come in each day and I need to run these emails against a master list to remove emails that I have already contacted. I'm am really not sure how this should function. Perhaps there is a master file with all emails that I have contacted. Each daily list could then be scrubbed against the master list and output only new emails. That basically explains the capability I need. You'll have to recommend how to set it up. One other request. It would be greatly beneficial to have the new emails, once scrubbed, output into text files where all emails are seperated by comma. csv files really won't work for me. I need the program to dump 25 emails per text file seperated by comma (example: email1,email2,email3, and so on up to 25; then the program needs to create a new output file) It is important that the output dump 25 emails per file so I can distribute these contact to follow-up representative throughout my network of marketers. Let me know if you have questions.
