SubstackvsSysteme.io

Substack made paid newsletters normal. You write, it sends, and readers can subscribe or pay in one click. The network effects are real: recommendations, Notes, the app, and discovery bring new readers you did not have to find. There is no monthly fee, and for a writer who wants to write rather than run software, that is a gift.

Systeme.io is a bargain of the all-in-one software category. In this comparison, it is also a clear alternative for a solo marketer who wants every marketing tool under one cheap login: a free plan that never expires with 2,000 contacts, unlimited email sends on every tier, a funnel builder with A/B tests and deadline timers, courses with drip and quizzes, an affiliate program manager, and zero transaction fees. When comparing pricing, plans, and cost, the math is hard to argue with.

Where they are different

Choose Substack when you want to write, get paid, and be discovered with the least possible setup.

Choose Systeme.io when you want its marketing features for funnels, courses, or webinars, and want affiliates promoting you at a reasonable cost.
