In my opinion, you should build your own website where you capture the names and email address of all people clicking through. I've seen people put auto responders on their page to capture the names and email address of people visiting before routing them through to the sales page of their affiliate program. The way I've seen this done is by giving people the incentive to give you their names and email addresses by offering them a free report or free relative content so that they click on the auto responder box and get directed to the affiliate sales page.

I've also seen this done using affiliate masking which directs the person who clicks to the sales page, but it will have your domain in the address bar and whatever title you put on the page. Good luck. Keep us posted with your results.
