Our Testing Methodology

We used all three platforms for 30 consecutive days in September 2026. We tested: onboarding time, ease of building a landing page, email deliverability, course creation, team collaboration, and real-world use cases for solopreneurs. We paid for the mid-tier plan on each platform (except Systeme.io, which we used on the free plan for the first 14 days).

Bottom Line

For building an online business: Systeme.io

It's the only platform that gives you everything in one place — landing pages, email marketing, courses, funnels, blog, and affiliate management. The free plan is genuinely usable (2,000 contacts, unlimited emails). And if you're looking to earn as an affiliate, the 60% lifetime recurring commission is unmatched in the industry.
