In the first email I first send them the link to the lead magnet a second time (the excuse to email them) and ask them if they saw the offer (affiliate link). I then go on and give a bullet point list of why I think they should get it as well as maybe 1 testimonial to give it credibility and start easing into the emotional realm. I'll usually finish with a question, opening a loop making them want to open the next email.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
