Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.
A relative newcomer that was only founded in 2014, ConvertKit has taken the world of email marketing by storm. According to the company, they now have nearly 20,000 active customers of their email services. Their affiliate program works by paying existing customers a lifetime 30 percent commission for referrals that subsequently become ConvertKit customers or who sign up for ConvertKit webinars and other digital products.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
