What they are
ConvertKit
Newsletter platform with landing pages, automated email sequences, paid newsletters, and a creator marketplace. Strong choice for selling digital products to a subscriber base. Now rebranded as Kit.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
