Is this against Clickbank’s rules?

I want to buy a domain, and direct link the hoplink to the domain. Basically just a redirect to the offer. I haven’t done much with Clickbank before, and want to know if this is inefficient/against the rules. In the past, I’ve only direct-linked hoplinks to text in emails with a fair amount of success but if I am going to scale, would the first method work with no landing page?

I don't think it's against the rules if you actually redirect to the offer and not iframing.

Just make sure your email marketing is can-spam compliant no scraped emails from the Internet.
