I am loading a CPA offer affiliate link into an iframe but when I did some test emails it doesnt open the second page after submitting the email into the form. It just says loading...
But when I do it without the iframe it works fine.
No idea, there would be no reason for this, if the landing page is showing up in the Iframe then there should be no problems. Although I have head running huge magnets on the side of your box will fix many unexplained problems!
Ive had that problem in the past and some offers were never able to convert because of the iframe.
Havent found out why this happens but I just use a meta refresh instead of iframing it(both kill referer)
Look at the source code of your offer. I ran into one earlier that actually said in the code that it wouldn't work in a frame. I think it was for a cash advance offer on Copeac, but I don't remember now.
