Substack vs. beehiiv vs. Kit: Which Platform Should You Pick?

Platform choice paralyzes new writers, but the honest truth is that all three of these will let you publish and grow. They just optimize for different things. Here's how to choose without spending a week on comparison spreadsheets.

Substack: simplest, best for writers who want an audience Substack is free to start and takes a 10% cut of paid subscriptions (plus Stripe fees). Its superpower is discovery — the Substack app, Notes, and the recommendation network surface your work to readers who don't know you yet. If you're a writer who wants paid subscriptions and network-driven growth without touching settings, Substack is the path of least resistance. The tradeoff: limited automation, basic segmentation, and you're building inside their walled garden.

beehiiv: best for growth and ad-based monetization beehiiv was built by ex-Morning Brew operators, and it shows. It has the strongest growth toolkit — a native recommendation network, a boosts marketplace where you can pay (or get paid) for subscribers, referral programs, and a built-in ad network that places sponsorships into your issues automatically. Paid plans start around $39–$99/month, but crucially they don't take a cut of your subscription revenue. If you're serious about scaling a media-style newsletter, beehiiv is usually the answer.

Kit: best for creators selling products Kit (formerly ConvertKit) is less a "newsletter platform" and more an email marketing platform for creators. Its strength is automation: visual sequence builders, tagging, and segmentation that let you send the right email to the right subscriber automatically. If you sell courses, digital products, or run a business where email is one channel among several, Kit's automations and commerce tools are worth the complexity. It has a free tier up to 10,000 subscribers.

The quick decision rule Want the fastest route to a paid audience and don't want to think about tooling? Substack. Building a scalable, sponsor-monetized media brand? beehiiv. Running a creator business where email drives product sales? Kit.

Don't over-optimize the first choice Migrating platforms later is annoying but entirely doable — all three let you export your list, and your subscribers come with you. The platform is not what determines whether your newsletter succeeds; consistency and a clear promise are. Pick the one that matches your goal today and start publishing.

The takeaway Substack for writers chasing an audience, beehiiv for growth-and-ads media plays, Kit for creators selling products. Any of them beats spending another week undecided.
