HELP! I'm looking for a way to block specific e-mail addresses from my broadcast lists. Is there a way that I could build a file that my lists would check against prior to sending the e-mail? I work for a company that is a direct mail distributor. We are looking to leverage our customer base of email addresses to mail certain "offers" to. We also have a few other lists that are of newsletter/information nature. If I have someone call in and request to be taken off the list, I want to make sure we don't mistakenly mail to them in the future. Currently we're housing the email addresses in a customer database and don't have the capability to suppress them at that stage. We're doing an extract and using ListServ as a vehicle to mail only (on specific lists)... on the newsletter side, listserv is doing the email address management. Can you provide any insight? Thanks, Tressa Graves
