What they are

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.

ConvertKit

ConvertKit is an email marketing platform aimed at bloggers, podcasters, course creators, and independent writers who need to grow and monetize a subscriber list. It combines email broadcasts, automated sequences, landing pages, and a paid newsletter feature in one place. The interface is simpler than enterprise tools like Mailchimp or ActiveCampaign, which makes onboarding fast but limits advanced design flexibility.
