There is no autoresponder included. There are many affordable autoresponder services out there that you can get when you need it, but building an email list definitely should not be the starting point for your business. That will come down the road, typically when your website is getting a sustainable source of traffic. You will be learning all about this as you move through the elite, industry leading training at Wealthy Affiliate.
The other type of Amazon affiliate link I use is when I’m mentioning a product in passing and/or a new product is announced. For example, when Nikon announced the Nikon D300s we immediately posted about the news because it was a notable and anticipated camera announcement. The camera was not yet available in stores and we were not able to get a review sample yet – but it was available for Pre-Order on Amazon so we linked to it.
Now most affiliate programs have strict terms and conditions on how the lead is to be generated. There are also certain methods that are outright banned, such as installing adware or spyware that redirect all search queries for a product to an affiliate's page. Some affiliate marketing programs go as far as to lay out how a product or service is to be discussed in the content before an affiliate link can be validated.
