Worth promoting product that asks for Email first?

Was looking for offers to promote and found something that looked decent to sent traffic to.
I was checking the the affiliate link on the order page and when you sign up, it asks for email adress first, so I put in my email.
Next day I get an email from this vendor with the typical sales stuff and a link to buy/sign up to his product.
I checked the order page and it says [affiliate=none].

Is it still worth promoting this, since he probably makes money from you yet you don't get a commision

This is common practise on clickbank

You are correct that you wouldn't get the commission, though it may not be malicious. [affiliate=none] implies the cookie was never put on your computer in the first place, or was deleted from your browser for some reason, or you used two different browsers.

If the vendor was up to shenanigans then normally you would see [affiliate=VendorsID]

It would be worth trying that website again with your affiliate hoplink, then if it still doesn't work get in touch with ClickBank about it.

I agree, it sounds like your cookie was not embedded in the first place. Perhaps Mancar can help us out here.

I promote a CB product that asks for an email first (as part of the sign-up process for an account). I know the company personally and am glad that they do this: My cookie lasts for 60 days. The vendor sends emails to people who fail to purchase promoting the product and getting them to buy it, and I get several sales from this. Because they send naked links in their emails it doesn't overwrite my cookie.

Basically, that is what you need to check for. Is your cookie being overwritten in the emails.
