I have a list of opt-ins. Many of those opt-ins go onto purchase my product and end up on my "customer list". I would like to eliminate these people from my "lead" list so they won't get promotions for a product they already bought. I know some of you may say "don't bother", but I really do have an important reason behind this request, so please help me if you can.
Does anyone know an easy way to compare an aweber subscriber list to a list of buyers (say of a clickbank product) and then remove the buyers from the aweber list?
Key point - these buyers are ALREADY on the "customer" list. I only want them on one list.
