I have a question to all you experts out there. I am not sure if this is doable or not but I will ask anyway.
I am getting ready to sell my mailing lists which is constantly growing and growing every day by around 100+.
Is there any way to sell my mailing list(s) to customers and when they buy it online for it to not only take paypal/card payment to also reckonise their ip address/e-mail so they can only use the list once?
Is there a way of me to sell my lists but instead of giving away my lists e-mail addresses where they can use again and again, to sell it to them where they can't steal the e-mail addresses?
