If an author publishes for free, Substack is 100% free with zero fees. Second, a one-time $50 custom domain setup fee charged to publications connecting branded web domains. Substack operates zero advertising networks, displays zero banner ads, and never sells or monetizes reader data, maintaining absolute structural alignment with editorial independence and reader trust.
