Clickbank product -How to ADD the buyer to Aweber- automaticlly -without them know??

I want to know, how i can Capture my clickbank product buyers in my aweber buyers list? - without them filling an optin form -

so automatically without them knowing.

like this

my sales page --> my Order page (clickbank order page) -->My thank you page

In this process, how can I automatically add this buyer to my Aweber buyer list?

I am on about Automatically- without the buyer going through any loops, or without them giving their email in an optin form.....



What are my options ? {would i need to purchase any software/ scripts?}

{I am asking for Clickbank products...... not RAP, or $7dss}

 

(Your sales page - A form in bottom asking visitor to put his name and email to get started) - Form submit button takes him to order page - > your thank you page.

The thing is this way you will get opt-ins but they still have to confirm your subscription, From aweber you can disable double optin however is that really what you want ?

 

You can do it but you have to change your cb transaction email to yours list email..
Search aweber, they have a write up about this.

 

I'm pretty sure aweber require double optin for emails imported via API, getresponse allow single optin via API but you have to request it specifically for your campaign.

 

Adding them automatically without them knowing will result in a higher spam rate
