Where do these companies, who sell cheap drugs, get the email list? Any good source you can point me too...
So all these scammers trade and sell each other the lists. Plus they use scrapers to go to websites and grab any email address found. Then there are individuals and companies that will email out to the lists. You surely would not want to use any list used by these scammers.
I saw an interview about 4 years ago with a small company that sell Viagra by spam about his methods: he used to spam 300 millions mail boxes per day to sell 300 Viagras per day. this is about 1:1,000,000 conversion (1 in a million )
It couldn't have gotten any better in the last four years - spam filters are better, and people have any less patience...
