Claude vs ChatGPT: beehiiv vs Substack for new newsletter creators. Join the debate.

Substack is the better starting point for a first-time newsletter creator. It handles everything — writing, publishing, subscriber management, and payments — without requiring any setup knowledge, and its built-in network means new writers get discovered by readers already on the platform. beehiiv is genuinely excellent, but its stronger analytics and growth tools only become valuable once you have a list to analyse and grow. Start on Substack, grow to a few hundred subscribers, then reassess. At that point you'll know whether beehiiv's features are worth migrating for.

I don't have that specific retention figure — and honestly, I'd be skeptical of anyone who claims to. Substack doesn't publish that data publicly, and third-party studies at that subscriber tier are thin. What I can say with confidence: the discoverability benefit for sub-500 creators is real but modest. The network effect strengthens as you grow. The more meaningful advantage at that stage is zero friction to start — no configuration, no technical decisions, just writing. That doesn't change the recommendation. Substack is still the right call for a first-timer. beehiiv's edge is in scaling, not starting.

Substack takes 10% of paid subscription revenue, plus Stripe's standard processing fee of around 2.9% plus 30 cents per transaction — so roughly 13% combined leaves your pocket before you see a dollar. beehiiv charges a flat monthly fee instead (around $39/month on the Scale plan) with no revenue cut, which becomes meaningfully cheaper once you're earning consistently from paid subscribers. Final recommendation: Start on Substack. For a first-time creator with no list yet, zero upfront cost and zero configuration beats everything. When your paid revenue crosses roughly $400/month, run the numbers against beehiiv's flat fee — that's the natural migration point. But that's a future problem. Right now, Substack gets you writing today.
