beehiiv vs Kit vs Substack (2026): Pick by How You'll Make Money

This comparison is based on official pricing pages and documented platform features as of September 2026, and we say so wherever we haven't tested something ourselves.

Most newsletter comparisons read like spec sheets. Features in, features out, "it depends" at the end. That misses the actual decision.

Your newsletter platform choice comes down to one question: how will this newsletter make money? A sponsorship-driven newsletter needs different tooling than a paid-subscription publication or a creator selling digital products. Pick the wrong platform for your revenue model and you'll pay for it twice: once in fees, once in migration pain.

Here's the one-line version:

• Kit fits creators selling products and courses, and it has the most generous free plan in the category (up to 10,000 subscribers).
• beehiiv fits sponsor-monetized and growth-focused newsletters, with a built-in ad network and a proper website builder.
• Substack fits writers building a paid subscription on top of audience, if you accept their 10% cut.

By the end of this post you'll know exactly which one fits your model. Every price below was checked on official pricing pages in September 2026; platform pricing changes, so re-verify anything before you commit a card to it.

Quick Verdict

• Best overall for product-sellers: Kit — free up to 10,000 subscribers, commerce tools built for creators.
• Best for sponsorship money: beehiiv — ad network, Boosts, and growth analytics native to the platform.
• Best for paid subscriptions with network reach: Substack — discovery effects are real, but it keeps 10% of your paid revenue.
• Skip all three if: you need enterprise marketing automation. These are creator platforms; look at ActiveCampaign or Customer.io instead.

The platforms, briefly

Kit (formerly ConvertKit)

Kit is the email platform built for creators: bloggers, podcasters, course sellers, YouTubers. It's been around the longest of the three (founded 2013 as ConvertKit) and it shows in the automation depth. The one thing it does better than anyone else in this trio: selling digital products directly from email with its commerce features. Free plan goes up to 10,000 subscribers, which is unusually generous. Paid plans start at $33/month billed yearly ($390/year) at the 1,000-subscriber tier, per Kit's pricing page in September 2026.

beehiiv

beehiiv is the newest of the three, built by early Morning Brew employees in 2021, and it's designed around one insight: newsletters are media businesses. That means an ad network, a sponsorship marketplace (Boosts), a referral program engine, and a real website builder. The free Launch plan caps at 2,500 subscribers. Scale, the entry paid plan, starts at $49/month at the 1,000-subscriber tier per beehiiv's pricing FAQ in September 2026.

Substack

Substack is the distribution network dressed as a newsletter tool. Free forever with no subscriber cap, built-in discovery, Notes for social reach, and readers who arrive expecting to pay for good writing. The trade: Substack keeps 10% of paid subscription revenue (plus standard payment processing). You're trading margin for their audience network.

Feature comparison

Deep dive: the four money models

This is the section that decides your platform. Pick your model.

Model 1: Sponsorships (brands pay to reach your list)

Winner: beehiiv. If sponsorships are your revenue, you want the platform that treats sponsors as a product. beehiiv's Ad Network matches newsletters with advertisers, Boosts let other newsletters promote you (paid placement), and its analytics show sponsors the numbers they ask for. Newsletter-growth agencies say the same: one of the largest told its audience beehiiv is its preferred ESP "particularly for beginners or if someone is building a sponsor-monetized newsletter." Kit can run sponsorships, but you'll assemble the machinery yourself.

Model 2: Paid subscriptions (readers pay monthly/yearly)

Winner: it's closer than you think. Substack keeps 10% of paid revenue; Kit and beehiiv keep none (you pay standard processor fees). On a $5/month publication with 100 paying readers, that's $600/year difference. But Substack's network discovery can add paying readers a standalone list never sees, and famous writers make the 10% cheap. The honest math: Substack's 10% crosses Kit's ≈$390/year fee at about $325/month of paid revenue (and beehiiv's ≈$588 at about $490/month). Below that, Substack's all-in cost usually wins; above it, every month you stay on Substack costs you more than a Kit or beehiiv subscription would. Kit's paid-newsletter support handles monthly, quarterly, and annual billing.

Model 3: Info products and courses (email is the delivery channel)

Winner: Kit. Course creators and digital-product sellers live in Kit. Commerce features sell products directly, tagging-based segmentation targets the buyers, and the automation builder runs multi-email launch sequences without add-ons. The agency voice again: Kit is where "an info product person can do more revenue... if they're dialed." beehiiv can sell subscriptions and some products; it isn't built as a commerce engine.

Model 4: Free list now, monetize later

Winner: Kit. The free-plan caps make this simple. Kit's free tier runs to 10,000 subscribers; beehiiv's Launch plan stops at 2,500. If you're in pure accumulation mode with no revenue yet, Kit gives you four times the runway before a paid plan enters your life. beehiiv counters with better free-tier growth tools (Boosts exposure), so if growth mechanics matter more than the cap, run your own numbers.

Pricing at three stages

Prices scraped from official pricing pages, September 2026. Both Kit and beehiiv scale pricing with subscriber count, so treat these as the 1,000-subscriber entry points.

That last row is the real comparison. Substack looks cheapest until you do revenue math; beehiiv costs the most up front but ships the tools that earn sponsorship income; Kit sits between, free the longest.

Pros and cons

Kit

• Free plan to 10,000 subscribers, the largest in the category
• Deepest automations and creator commerce in the trio
• Built for and by creator workflows; large integration ecosystem
• Paid tier costs arrive earlier than Substack's $0
• Website/builder story is weaker than beehiiv's
• Commerce fees apply on product sales (processor-level)

beehiiv

• Sponsorship-first: Ad Network, Boosts, referral engine
• Real website builder and strong analytics
• Fastest-moving product of the three
• Free plan caps at 2,500 subscribers
• Highest entry paid price ($49/mo at 1k)
• Automations and commerce trail Kit

Substack

• $0 platform cost at any list size
• Discovery network and Notes drive organic growth
• Readers already understand the paid-subscription model
• 10% of paid revenue, forever, plus processor fees
• Minimal design, automation, and analytics
• No product commerce beyond paid posts

Who should choose what

Choose Kit if you: sell courses or digital products, run launch sequences, want the longest free runway, or came from Mailchimp wanting something creator-native.

Choose beehiiv if you: chase sponsors or ads as the revenue line, want a publication website, or plan aggressive paid-growth mechanics like Boosts and referrals.

Choose Substack if you: are a writer first, want network discovery, have (or want) a famous name, and can tolerate 10% on paid revenue for the reach.

The verdict

There is no single winner here, and any post claiming otherwise is selling you something. The data points one way per model: Kit for product-sellers and free-list builders, beehiiv for sponsorship businesses, Substack for paid-subscription writers leveraging network effects.

If you want our default for the broadest set of new creators starting from zero in 2026: Kit. The 10,000-subscriber free plan means you pay nothing through the entire validation phase, and the commerce tools mean the transition to earning doesn't require a platform migration, which is the decision people most regret.
