Beehiiv vs Substack vs Kit: Newsletter Platforms Compared (2026)
The newsletter renaissance is alive and well in 2026. More creators are building email-first businesses than ever, and three platforms dominate the conversation: Beehiiv, Substack, and Kit (formerly ConvertKit). They all send emails, but they approach the newsletter business from completely different angles.
I’ve helped creators migrate between all three, run newsletters on two of them, and watched their pricing evolve. Here’s what actually matters when choosing.
Quick Comparison Table
| Feature | Beehiiv | Substack | Kit (ConvertKit) |
|---|---|---|---|
| Pricing | Free–$99/mo | Free (10% of paid subs) | Free–$66/mo |
| Monetization | Ads, paid subs, boosts | Paid subscriptions (10% cut) | Digital products, tips, paid newsletter |
| Custom domain | Yes (all plans) | No (substack.com subdomain) | Yes (paid plans) |
| Growth tools | Referral program, boosts, recommendations | Reader network, recommendations | Landing pages, email courses |
| Automation | Basic sequences | None | Advanced visual automations |
| Landing pages | Built-in | Built-in (limited) | Advanced, multiple per account |
| Analytics | Detailed (clicks, UTMs, demographics) | Basic (opens, subscribers) | Good (tag-based, automations) |
| Deliverability | Excellent | Excellent | Excellent |
Pricing at Scale
This is where it gets interesting. The “free” platforms aren’t always cheapest:
| Subscribers | Beehiiv | Substack | Kit |
|---|---|---|---|
| 1,000 | Free | Free | Free |
| 5,000 | $49/mo (Growth) | Free | $66/mo |
| 10,000 | $49/mo (Growth) | Free | $100/mo |
| 50,000 | $99/mo (Scale) | Free | $259/mo |
But wait: Substack’s “free” is misleading if you monetize. At 1,000 paid subscribers paying $10/month, Substack takes $1,000/month. Beehiiv at $99/month with Stripe’s 2.9% processing fee costs you roughly $390. Kit would charge around $166/month total. Substack is only “free” if you never charge your readers.
Beehiiv: Best for Growth-Obsessed Creators
Pricing: Free (up to 2,500 subs). Growth at $49/mo. Scale at $99/mo.
Beehiiv was built by ex-Morning Brew employees, and it shows. Every feature is designed to grow your list faster. The referral program (think: “refer 3 friends, get a free ebook”) is built-in and works out of the box. No third-party tools, no code.
The Boost Network is Beehiiv’s secret weapon. You can pay other Beehiiv newsletters to recommend yours, or earn money by recommending others. It’s basically a subscriber acquisition marketplace. Creators report costs of $1-3 per subscriber through Boosts: significantly cheaper than paid ads.
The ad network is another revenue stream. Even if you don’t charge for subscriptions, Beehiiv connects you with advertisers looking to reach your audience. You set your CPM, they fill the spots. It won’t replace a day job at 5,000 subscribers, but it’s meaningful income at 25,000+.
The editor is clean and modern. A/B test subject lines, segment your audience by engagement, and track exactly which links get clicked. The analytics are the best of the three platforms.
Where Beehiiv falls short: automation. You can set up basic welcome sequences, but there’s nothing close to Kit’s visual automation builder. If you need complex drip campaigns that branch based on behavior, Beehiiv isn’t there yet.
Beehiiv is ideal for creators who prioritize audience growth above all else and plan to monetize through ads or paid subscriptions.
Substack: Simplest Path to Paid Subscriptions
Pricing: Free forever. Substack takes 10% of paid subscription revenue (plus Stripe’s 2.9% + 30¢).
Substack’s pitch is radical simplicity. Sign up, write, publish. There’s no configuration, no segments, no automations. You write posts, readers subscribe, and some of them pay. That’s it.
The built-in reader network is Substack’s biggest growth advantage. When someone subscribes to one Substack newsletter, the platform recommends others. This network effect drives organic discovery that doesn’t exist on Beehiiv or Kit. Popular Substacks report 20-40% of new subscribers coming from recommendations.
The reading experience matters too. Substack has become a destination: readers open the Substack app, browse their subscriptions, and discover new writers. It’s part newsletter platform, part social media. Comments, notes, and restacks (shares) create engagement loops that pure email platforms can’t replicate.
The 10% cut is Substack’s biggest drawback. At small scale, it’s fine: 10% of nothing is nothing. But successful writers doing $10,000+/month in subscriptions are handing Substack $1,000+ monthly. That’s more expensive than any alternative at scale.
You also give up control. No custom domain. No advanced analytics. No automation. No self-hosted email list you can export to another tool easily (you can export subscribers, but not payment relationships). You’re building on Substack’s platform, not your own.
Substack works best for writers who want simplicity above everything else, plan to monetize through paid subscriptions, and value the built-in discovery network.
Kit (ConvertKit): Best for Selling Digital Products
Pricing: Free (up to 10,000 subs, limited features). Creator at $29/mo (1,000 subs). Creator Pro at $59/mo (1,000 subs). Scales with subscriber count.
Kit is the email marketing platform that rebranded from ConvertKit in 2024. Unlike Beehiiv and Substack, which are newsletter-first platforms, Kit is a full creator business platform. Newsletters are one piece of a larger toolkit that includes landing pages, digital product sales, and advanced automation.
The automation builder is Kit’s crown jewel. Visual workflows that trigger based on link clicks, purchases, tag additions, or time delays. You can build sophisticated funnels: new subscriber → welcome sequence → segment by interest → pitch relevant product → follow-up based on whether they bought. Neither Beehiiv nor Substack can do this.
Commerce is built in. Sell ebooks, courses, templates, coaching packages, and memberships directly through Kit. No need for Gumroad or Teachable: Kit handles payments, delivery, and even affiliate programs. For creators whose business model is “grow email list → sell stuff to list,” Kit is the most integrated solution.
Landing pages and forms are more advanced than either competitor. Multiple opt-in pages with different designs, embedded forms for your existing website, and tag-based segmentation from the moment someone subscribes.
The downside? Kit doesn’t have Beehiiv’s growth tools or Substack’s discovery network. Growing your list means driving your own traffic through SEO, social media, or collaborations. There’s no built-in boost network or reader app sending you subscribers.
Kit is ideal for creators who sell digital products, courses, or services, and need sophisticated email automation to nurture and convert their audience.
Which Platform Fits Your Goals?
“I want to grow as fast as possible” → Beehiiv. The boost network, referral program, and recommendations engine are purpose-built for subscriber acquisition.
“I just want to write and get paid” → Substack. Zero setup, built-in payments, and a reader network that brings you audience. Accept the 10% cut as the cost of simplicity.
“I sell digital products or courses” → Kit. The automation builder and built-in commerce make it the best platform for creators with products to sell.
“I’m starting from zero and want free” → Substack if you plan to do paid subscriptions. Beehiiv’s free plan if you want growth tools. Kit’s free plan if you want landing pages and basic automation.
“I’m at 50,000+ subscribers” → Beehiiv or Kit. Substack’s 10% becomes prohibitively expensive at this scale.

FAQ
Can I switch platforms without losing subscribers? Yes: all three let you export your subscriber list as a CSV. What you lose is payment relationships (paid subscribers on Substack won’t auto-transfer to Beehiiv), automation workflows, and historical analytics. Plan for some subscriber churn during migration (typically 5-15%).
Which platform has the best deliverability? All three have excellent deliverability in 2026. They’ve invested heavily in sender reputation, authentication (DKIM, SPF, DMARC), and inbox placement. The differences are negligible for most creators. Your content and sending frequency matter more than the platform.
Can I use a custom domain with Substack? No. Your newsletter lives at yourname.substack.com. This is a dealbreaker for some creators who want to build brand equity on their own domain. Beehiiv and Kit both support custom domains on paid plans.
Is Kit still called ConvertKit anywhere? The company officially rebranded to Kit in 2024, but you’ll still see “ConvertKit” in older reviews, integrations documentation, and some billing pages. It’s the same product, same team, same platform: just a shorter name.
What if I want to run both a free newsletter and sell courses? Kit is the clear winner here. You can run a free newsletter, segment subscribers by interest, and sell courses directly through the platform. Beehiiv can handle the newsletter but you’d need a separate course platform. Substack only supports paid subscription content, not standalone product sales.
