Kit vs Substack vs Beehiiv: The Honest 3-Way Comparison
TL;DR
Beehiiv wins for operators who want zero revenue cuts and serious growth tooling, Kit wins if automation and product funnels are the core use case, and Substack is a distribution bet that slowly converts your audience into a tenant relationship you can't easily exit.
Every RevOps team eventually gets the same request from a founder or content lead: “we should start a newsletter.” I’ve had this conversation with B2B SaaS clients more times than I can count, and the answer keeps getting murkier as Substack grows its cultural cachet, Beehiiv matures into a serious media operating system, and Kit (formerly ConvertKit) doubles down on creator commerce. The differences that matter aren’t the features listed on a pricing page. They’re what happens when you want to leave, who takes a cut when you charge subscribers, and whether your SEO equity lives on your domain or theirs.

How to choose
The real question is simple: which platform treats your audience as your asset versus as a shared resource it gets to monetize alongside you? Kit and Beehiiv both let you export your full list, use your own domain from day one, and keep the economics of a paid newsletter largely intact. Substack makes discovery easier early on and charges you permanently for it.
For B2B newsletters running as a demand gen channel, automation depth matters as much as deliverability. Kit’s sequences and tagging logic connect naturally with CRMs like HubSpot or Pipedrive in ways Beehiiv doesn’t yet match. But if the newsletter itself is a revenue line, or you’re building a media property, Beehiiv’s 0% take rate and referral infrastructure compound hard at scale. Do the math: at 1,000 paid subscribers at $10 per month, Substack’s 10% cut costs you $1,200 per year. At 5,000 paid subscribers, that’s $6,000 per year in platform fees paid to a landlord, and every dollar of that audience equity lives on real estate you don’t own.
My clients who started on Substack because it felt free almost universally wish they’d picked a destination platform first. The migration pain is real and it’s not just technical.
You should pick Kit if your newsletter is one node in a larger automation funnel: you’re selling a course, a cohort, a SaaS product, or a service, and you need sequences, tags, and product checkout to live in the same system. Kit’s integrations with Zapier and its native commerce layer make it the right substrate for creator-led go-to-market. Don’t bother bolting a third-party referral tool onto Kit either; if referral growth is a priority, go to Beehiiv instead.
You should pick Beehiiv if the newsletter is itself the product or the primary distribution channel, you want analytics you can actually act on, and you’re planning to monetize via paid tiers or sponsorships. The Beehiiv ad network also gives you a third monetization lever that neither Kit nor Substack can match. The $99/month Scale plan pays for itself fast once you have even 500 paid subscribers at $10/month.
You should pick Substack only if you’re starting from zero, have no existing list, and want the network’s discovery engine to do early acquisition work. Treat it as a launchpad, not a home. Set a migration trigger before you even publish your first issue, something like: “When I hit 200 paid subscribers, I move.” That threshold is low enough that the migration is still manageable.
The ownership question decides everything
After running this evaluation for multiple clients at Homegrown Growth Co., the pattern is consistent: the platform that feels cheapest at launch is almost always the most expensive at maturity. Beehiiv’s pricing documentation is unusually transparent about what each tier actually unlocks, and that 0% fee structure on Scale is genuinely differentiated from anything else in this category. Kit’s automation documentation shows how deep the sequencing logic goes, which matters when your newsletter is feeding a product funnel rather than standing alone.
Pick based on where you intend to be in 18 months. Not where you are today. Migrating a paid subscriber list mid-flight is the kind of operational problem that costs more in lost momentum, subscriber churn, and team hours than any monthly platform fee you were trying to dodge in month one.
Frequently asked questions
Does Substack let you export your subscriber list?
Yes, Substack lets you export a CSV of subscribers, but you lose the payment relationships and Substack keeps its network data. Migrating paid subscribers away is operationally painful.
What percentage does Beehiiv take from paid subscriptions?
Beehiiv charges 0% transaction fees on paid subscriptions across all paid plans. You keep 100% of subscription revenue minus Stripe's standard processing fee.
Is Kit good for selling digital products?
Kit has a native commerce layer for selling digital products and tip jars directly, with no platform fee on sales. It suits creators who want automation plus product sales in one place.
Can you use a custom domain on Substack?
Substack supports custom domains on its paid Author Pro plan, but your publication still lives inside Substack's ecosystem and SEO authority flows to their domain by default unless configured.
Which newsletter platform is best for B2B operators?
Beehiiv is the strongest choice for B2B operators who want analytics, referral programs, and monetization without platform dependency. Kit wins if you need deep automation tied to a product funnel.
