Hello I apologize if in wrong category.

I am in the process of setting up an affiliate ppc campaign.
I would like to know how to do the following.

Add a link to my landing page that captures their email address and at the same time sends them to the offer and that they understand the publisher needs their email so that they don't say I just typed in my email. What is the best way to do this?

Thank you.

What your doing is the only way but it takes so much time to collect mails unless you have great traffic on landing page.

Good luck.

You replied it is the only way. My question was how do I do this? You did not answer my question.
