Hi. I have some good optin data and Im willing to sell it but IDK what price should I ask for it? The data are fresh with all fields included like: billing name, billing address, IP, site of subscription, phone, email address, etc. Also I have various niches. Building your own list will take you forever and also SEO is hard for pharma niche as major seo service do not work out pharma niche and CPC is high for keywords pharma. What do you think?
