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.
In April 2008 the State of New York inserted an item in the state budget asserting sales tax jurisdiction over Amazon.com sales to residents of New York, based on the existence of affiliate links from New York–based websites to Amazon. The state asserts that even one such affiliate constitutes Amazon having a business presence in the state, and is sufficient to allow New York to tax all Amazon sales to state residents. Amazon challenged the amendment and lost at the trial level in January 2009. The case is currently making its way through the New York appeals courts.
