How this works.

There are many programs on the internet that make mailing lists for advertisers. These programs (sites) send ads from their supporters to the registered users who have signed up at these programs. "Now who would be dumb enough to sign up for receiving ads at his e-mail?" You could say. that's what it is about - these programs pay their members! Although the purpose is one - to get money for reading ads - there are different sites, so the payment systems are also  different. there the usual types:

• PTR - pays you when you open a received e-mail and click on the link within. -most common type.
• PTC - pays for clicking on banners, links. -also very common.
• Surveys - sends you an e-mail with a survey an gives you rather big amount of cash -unfortunately they send these mails VERY rarely so don't waste your time with these.
• PTP - you get paid for putting a link in your (or someone else) website -not worth while  if your traffic is beneath 500-a-day .
• Autosurf - you just run it, sit back and watch your money counting in - my favourite :)

Where the money comes from.

Advertisers pay to these programs to be advertised. and the program pays to its members to read these ads. Very simple :)
