For CPA marketing:
1) What is the best way to get visitor's email address (or ZIP submit) without irritating them for inputting their email address twice i.e. first at my landing page and second at advertiser's page.
2) Is there a way of using iFrame or some other technique where visitors enter email once (on my landing page or advertiser's page) and it (email) is saved both for me and advertiser?
I am just thinking that for building my email list the visitor could just get annoyed and close the advertiser's page without getting converted.
Would be great to know how warriors would handle this.
Thanking you in anticipation.
