beehiiv vs Substack vs ConvertKit: Which Newsletter Platform Wins?
The beehiiv vs Substack vs ConvertKit question comes up constantly because these three platforms solve the same problem in three genuinely different ways. Substack is a network-first publishing platform. beehiiv is a growth-and-monetization engine for serious newsletter operators. ConvertKit — now branded Kit — is an email marketing tool that happens to do newsletters well. We compared them across the three things that actually decide the winner: growth, monetization and cost.
There's no universal "best" here. The right pick depends on whether you're a writer who wants zero friction, an operator building a media business, or a creator who sells products alongside the newsletter.
beehiiv vs Substack vs ConvertKit: the comparison table
| beehiiv | Substack | ConvertKit / Kit | |

| Free plan | Yes, up to ~2,500 subs | Yes, unlimited subs | Yes, up to ~10,000 subs (limited features) |

| Automation | Light | Minimal | Strong (tags, sequences, visual flows) |
| You own the audience? | Yes (export anytime) | Yes, but discovery is tied to the network | Yes (export anytime) |
Pricing, subscriber limits and revenue shares change often and are approximate at time of writing. Confirm current terms on each platform before deciding. Note: Substack is included for comparison only — it does not run an affiliate program, so there's no affiliate link below.
Who wins for growth
Growth is where the platforms diverge most sharply. Substack's advantage is its network: the discovery feed, Notes and recommendations can send readers your way with no effort on your part, which is powerful when you're starting from zero. The catch is that this growth is borrowed — it lives inside Substack's ecosystem, and the audience discovers you through the platform rather than through channels you control.
beehiiv attacks growth with tools instead of a feed: a strong referral program, a recommendation network and paid "boosts" that let you acquire subscribers from other newsletters. It's more hands-on but more controllable. ConvertKit sits in the middle — its creator recommendations and best-in-class forms and landing pages help, but growth is largely something you drive with your own traffic.
Winner: a tie between Substack (effortless network reach) and beehiiv (controllable, compounding growth tools). Choose Substack if you want discovery handed to you; choose beehiiv if you want to own the growth engine.
Substack Best for effortless discovery
Substack's network — the discovery feed, Notes and recommendations — can grow your list with almost no effort, which is why so many writers start here. For transparency: Substack does not run an affiliate program, so the link below is a plain reference, not an affiliate link.
- PRO: A free, unlimited-subscriber plan plus a built-in social network that drives organic discovery you don't have to engineer.
- CON: The flat 10% cut of paid-subscription revenue gets expensive at scale, and there's essentially no automation or custom-domain flexibility.
beehiiv Best for serious growth & monetization
Referrals, a recommendation network and a built-in ad network make beehiiv the strongest pick for treating a newsletter like a real media business.
- PRO: The most complete growth-and-revenue toolkit of the three, including an ad network you don't have to sell yourself.
- CON: Paid tiers cost more than starting on Substack, and automation is lighter than ConvertKit's.
Who wins for monetization
If your plan is purely paid subscriptions and you want the simplest possible path, Substack is frictionless: turn on paid, and it handles billing. But that convenience costs a flat 10% of your subscription revenue on top of payment processing — which grows into real money as you scale.
beehiiv offers paid subscriptions plus something the others don't: a built-in ad network that matches sponsors to your newsletter automatically, so even free subscribers can generate revenue. ConvertKit/Kit shines for creators who monetize beyond a paywall — it can sell digital products, courses and accept tips directly, and its automation lets you run product launches to segments of your list. If a newsletter is one part of a broader product business, that flexibility wins.
Winner: beehiiv for newsletter-native revenue (ads + subscriptions), ConvertKit for creators selling products alongside the list.
ConvertKit / Kit Best for creators who sell
Beyond newsletters, Kit sells digital products and runs automated launches — ideal if the newsletter feeds a wider product business.
- PRO: The strongest automation and commerce features here — tags, sequences, product sales and a free plan that scales to ~10k subscribers.
- CON: The newsletter editor is plainer than Substack's or beehiiv's, and it lacks a built-in discovery network for organic growth.
Who wins for cost
Cost depends entirely on your stage and revenue model:
- Just starting, no revenue: Substack is $0 with unlimited subscribers, which is unbeatable if you don't yet need automation or a custom domain. Kit's free plan (to ~10k subs) is close behind for creators.
- Growing free newsletter: beehiiv's free tier (to ~2,500 subs) plus its ad network can turn revenue-positive before you pay anything.
- Earning from paid subscriptions: Substack's 10% cut is cheap at low revenue but expensive at scale — at some point a flat monthly fee on beehiiv or Kit costs far less than 10% of a large subscription income.
The honest summary: Substack is cheapest to start and gets relatively pricier as paid revenue grows; beehiiv and Kit cost more upfront but cap your platform cost as you scale. For a full spreadsheet-level view of the numbers, run your own subscriber count against each plan — none of these platforms guarantees revenue, and the cheapest tool is worthless if it's the wrong fit.
The verdict on beehiiv vs Substack vs ConvertKit

All three let you export your list, so you're never fully locked in — but migrating mid-growth is a hassle, so pick for the next year, not just this week. If you land on beehiiv, our beehiiv newsletter tutorial walks you through your first send.
