ConvertKit vs Beehiiv vs Substack for Newsletters

Picking a newsletter platform sounds easy until you actually try to do it.

At first, they all look close enough: write emails, collect subscribers, maybe charge for subscriptions, maybe publish to the web. Done. But once you’re in it for a few months, the differences get very real. One tool feels smooth until you need automation. Another grows fast until the pricing starts to sting. Another is beautifully simple right up until you want more control.

I’ve used all three in some form, and the reality is this: they are not interchangeable. They’re built for different kinds of newsletter businesses, and if you pick the wrong one, you usually feel it after you’ve already moved your list.

So if you’re trying to figure out ConvertKit vs Beehiiv vs Substack, here’s the short version first.

Quick answer

If you want the fastest, simplest way to start writing and maybe charge readers, Substack is the easiest.

If you want a newsletter platform built for growth, referrals, ad/network options, and media-style publishing, Beehiiv is usually the better pick.

If you want email marketing depth, automation, segmentation, and more control over your audience, ConvertKit is the strongest option.

That’s the quick answer. But which should you choose in practice?

• Choose Substack if you’re a writer first and don’t want to think much about software.
• Choose Beehiiv if you want to build a newsletter business and care about growth loops.
• Choose ConvertKit if your newsletter is part of a broader creator business, product funnel, or audience system.

The key differences aren’t really about “who has more features.” They’re about what kind of work the platform wants you to do.

What actually matters

Most comparison posts get stuck listing features. That’s not usually what decides things.

What matters is this:

1. How you plan to grow

If your growth comes from writing good posts and letting a built-in network help a bit, Substack makes sense.

If your growth plan includes referrals, recommendation swaps, landing pages, ad opportunities, and treating the newsletter like a media property, Beehiiv has a real edge.

If your growth comes from lead magnets, funnels, sequences, tags, automations, and selling products or services, ConvertKit is stronger.

2. How much control you want

Substack is intentionally opinionated. That’s part of the appeal.

Beehiiv gives you more room to build a publication.

ConvertKit gives you more control over email behavior and subscriber journeys.

The trade-off: more control usually means more setup.

3. How you’ll make money

This is a big one.

Substack is optimized for paid newsletters. It’s very good at getting a writer from zero to “I have paying readers.”

Beehiiv is better if you want multiple revenue paths: subscriptions, ads, sponsorships, referral growth, maybe even running several publications.

ConvertKit works well if your newsletter supports a business that makes money elsewhere: courses, coaching, digital products, memberships, consulting.

4. Whether your newsletter is the business—or part of the business

This is probably the cleanest way to think about it.

• On Substack, the newsletter often is the business.
• On Beehiiv, the newsletter is often a media business.
• On ConvertKit, the newsletter is often part of a creator business.

That sounds subtle, but it changes everything.

5. The cost curve over time

A lot of people compare starting prices and stop there. Mistake.

The real cost question is: what happens when you have 10,000, 25,000, or 100,000 subscribers?

Substack feels cheap early because there’s no big upfront software bill. But if you charge for subscriptions, the platform fee takes a cut of revenue. That can become expensive if you do well.

ConvertKit can get expensive as your list grows, especially if you’re using it like a full email marketing platform.

Beehiiv is often attractive in the middle ground for newsletter operators focused on scale, though pricing depends a lot on plan and publication setup.

In practice, “cheap” depends on your model.

Comparison table

Here’s the simple version.

Platform	Best for	Biggest strength	Biggest weakness	Monetization fit	Growth fit	Control level
ConvertKit	Creators, coaches, educators, product sellers	Automation, segmentation, creator tools	Can get pricey as list grows; less media-native	Great for products, funnels, launches	Good, but less built-in virality	High
Beehiiv	Newsletter businesses, media-style publications, startups	Growth features, referrals, publication focus	Some features feel built for operators more than casual writers	Strong for ads, subs, sponsorships	Excellent	Medium-high
Substack	Solo writers, journalists, essayists	Simplicity and fast paid newsletter setup	Less control, weaker advanced email tools	Excellent for paid subscriptions	Okay, mostly content/network-driven	Low-medium

If you want the one-line version:

• ConvertKit = best for running email like a business system
• Beehiiv = best for growing a newsletter like a media company
• Substack = best for just writing and publishing without friction

Detailed comparison

ConvertKit

ConvertKit has always made the most sense to me when the newsletter is connected to something else.

Maybe you sell a course. Maybe you run workshops. Maybe you’re a designer with templates, a founder with a waitlist, or a consultant trying to nurture leads. In those cases, ConvertKit feels natural because it thinks in terms of subscribers, forms, sequences, tags, automations, and offers.

That matters more than it sounds.

With ConvertKit, you can do things like:

• send different emails based on what someone clicked
• tag people by interest
• build onboarding sequences
• pitch products to one segment and not another
• create lead magnets and deliver them automatically

That’s standard email marketing territory, and ConvertKit does it well without becoming enterprise software.

Where it wins:

• automation is much better than Substack and generally more mature for email marketing use cases than Beehiiv
• segmentation is useful and practical
• forms and landing pages are easy to set up
• it fits creators who monetize beyond subscriptions

Where it loses:

• it’s not the most exciting platform for newsletter-native growth
• the publishing experience is fine, but not special
• pricing can creep up as your list grows
• if all you want is “write post, send email, maybe charge for access,” it can feel like too much tool

A contrarian point here: people often recommend ConvertKit as the “serious” option by default. I don’t think that’s always true. If your newsletter is editorial first and growth-focused, ConvertKit can actually feel less aligned than Beehiiv. Serious doesn’t always mean more automation.

Another thing: ConvertKit is not trying to be a social writing platform. That’s good if you value ownership and systems. It’s less good if you want discovery built into the product.

Best for

• creators with products
• educators
• consultants
• startups with lead capture and onboarding needs
• anyone who wants email logic, not just publishing

Less ideal for

• writers who want a dead-simple publishing workflow
• newsletter-first media brands chasing viral growth loops

Beehiiv

Beehiiv feels like it was built by people who understand that newsletters are often media businesses now, not just email lists.

That changes the product in useful ways.

The platform leans hard into growth: referrals, recommendations, audience expansion, publication tools, monetization options, and features that make sense if you’re trying to build a serious newsletter operation. If ConvertKit feels like “email marketing for creators,” Beehiiv feels more like “newsletter operating system.”

That’s why a lot of startup newsletters, niche media brands, and operator-led publications end up there.

Where Beehiiv wins:

• growth features are strong
• referral program setup is better than what most people want to cobble together elsewhere
• the publication model makes sense if you care about web + email together
• monetization options are broader than many people expect
• it feels built for newsletter-first businesses, not retrofitted for them

Where it loses:

• if you need deep behavioral automation, ConvertKit is still stronger
• some parts feel a bit “operator-ish” rather than writer-friendly
• if you don’t care about growth mechanics, some of the value is wasted
• it’s not as simple as Substack

Beehiiv is often the best for people who already know they want to grow aggressively. That’s the key. If you’re the kind of person who likes looking at referral rates, signup sources, audience cohorts, and sponsorship inventory, Beehiiv makes sense fast.

But here’s the contrarian point: not everyone needs Beehiiv, even if it looks more modern. I’ve seen solo writers move to it because everyone on X talks about it, then barely use the growth tools that justified the switch. If you aren’t going to use referrals, cross-promotion, monetization features, or publication analytics, you may just be paying for ambition.

Still, when Beehiiv fits, it really fits.

Best for

• newsletter startups
• media-style publications
• operator-creators
• founders building audience-led growth
• teams that care about growth systems

Less ideal for

• pure writers who want minimal setup
• people needing advanced email automations first

Substack

Substack’s superpower is that it removes excuses.

You can start fast. The editor is simple. Publishing is straightforward. Paid subscriptions are easy to turn on. There’s less software-brain involved, which is exactly why many good writers stick with it.

And honestly, that simplicity is underrated.

A lot of people don’t need a “platform strategy.” They need to publish consistently. Substack is very good at lowering the friction between “I have an idea” and “this is in readers’ inboxes.”

Where Substack wins:

• easiest to start
• clean writing and publishing flow
• built for paid newsletters from day one
• good fit for solo writers and personality-driven newsletters
• less setup, less tinkering

Where it loses:

• weaker automation and segmentation
• less control over branding and broader business setup
• if you want your newsletter integrated into a more complex business, it starts to feel limiting
• platform fees matter if paid subscriptions become meaningful revenue

Substack also has a network effect that’s real, but often overstated. Some writers do get discovery from the ecosystem. Many don’t get enough for it to be a deciding factor. So I wouldn’t choose Substack because you think the platform itself will grow you.

I’d choose it if you want the easiest path to writing and charging readers.

Another contrarian point: people sometimes dismiss Substack as “not serious” because it’s simpler. I think that’s backwards. Simplicity is a feature. If your business model is literally “write sharp stuff people pay to read,” Substack might be the most serious choice because it removes distractions.

Best for

• solo writers
• journalists
• essayists
• niche experts with a loyal audience
• people testing a paid newsletter quickly

Less ideal for

• teams with advanced workflows
• creators selling lots of different products
• businesses that need detailed segmentation and automation

Real example

Let’s make this less abstract.

Scenario 1: a two-person startup newsletter

Say you run a B2B SaaS startup. Two people on the team own the newsletter. The goal is not just “write interesting things.” The newsletter supports brand, top-of-funnel growth, and eventually sponsorship revenue.

You care about:

• landing pages
• referral growth
• analytics
• monetization later
• maybe multiple newsletters down the line

In that case, I’d usually pick Beehiiv.

Why not ConvertKit? Because while ConvertKit handles email logic better, this use case is more publication and growth oriented than funnel oriented. Beehiiv fits the shape of the business better.

Why not Substack? Because the team will likely want more control, more growth tooling, and a more business-like setup.

Scenario 2: a solo writer with 2,000 loyal followers

You’re a writer, analyst, or journalist with an audience on X, LinkedIn, or YouTube. You want to publish one free piece a week and one paid piece a week. You do not want to build automations. You do not want to mess with funnels. You mostly want to write.

Pick Substack.

That’s exactly what it’s good at.

Could you use Beehiiv? Sure. Could you use ConvertKit? Also yes. But in practice, both may add setup and decisions you don’t need.

Scenario 3: a creator selling a course and templates

You have a newsletter, a lead magnet, a mini-course, a flagship course, and occasional launches. You want people who download one thing to get one sequence, buyers to get another, and inactive subscribers to get cleaned or re-engaged.

That’s ConvertKit all day.

This is where ConvertKit earns its keep. It’s not just sending newsletters. It’s managing audience relationships and revenue paths.

Scenario 4: a developer building in public

This one is interesting.

A solo dev writing about what they’re building could go either way.

If the main goal is audience + future product sales, I’d lean ConvertKit.

If the goal is turning the newsletter itself into a media-ish asset with referrals and sponsorships, I’d lean Beehiiv.

If the goal is just writing updates and maybe charging for deeper posts, Substack is enough.

That’s why “which should you choose” depends less on your job title and more on how the newsletter makes money.

Common mistakes

There are a few mistakes people make over and over with these platforms.

1. Choosing based on what feels popular

Beehiiv has a lot of momentum. Substack has cultural momentum. ConvertKit has creator credibility.

None of that matters if the platform doesn’t fit your model.

Use-case first, platform second.

2. Overvaluing features you won’t use

This is probably the biggest one.

People say they want advanced automation, then send the same broadcast every week.

Or they say they need referral growth, then never set up a referral program.

Or they choose Substack for discovery and then realize most of their growth still comes from social and partnerships.

Be honest about your next 12 months, not your imagined future company.

3. Ignoring migration pain

Moving a newsletter later is possible, but it’s annoying enough that you should avoid doing it casually.

Imports, domains, automations, archives, signup forms, custom fields, subscriber states, paid memberships—none of it is impossible, but none of it is fun either.

So don’t choose too quickly just because setup takes five minutes.

4. Thinking “paid newsletter” automatically means Substack

Substack is great for paid newsletters, yes.

But if you want a paid newsletter plus sponsorships, partnerships, referrals, and a broader media strategy, Beehiiv may be better.

And if the newsletter is one monetization layer among products and funnels, ConvertKit can be the smarter move.

5. Looking only at startup pricing

Cheap at 1,000 subscribers can become expensive at 30,000.

Or the opposite: a platform fee that seems harmless at first can become painful once paid subscriptions scale.

Run the math on the business you want, not the audience size you have today.

Who should choose what

Here’s the clearest guidance I can give.

Choose ConvertKit if…

• your newsletter supports a creator business
• you sell products, services, courses, or memberships
• you care about automation and segmentation
• you want more ownership over subscriber journeys
• email is part of a funnel, not just a publication

This is the best for creators who think in systems.

Choose Beehiiv if…

• you’re building a newsletter-first business
• growth is a priority, not a side benefit
• you want referrals, recommendations, and media-style tools
• you may run sponsorships or scale into a publication
• you want something more publication-native than ConvertKit

This is the best for operators and newsletter businesses.

Choose Substack if…

• you want to start publishing immediately
• you’re a writer first
• your main monetization path is paid subscribers
• you don’t want to spend time configuring tools
• simplicity matters more than control

This is the best for solo writers who want less friction.

If you’re stuck between two

A simple tiebreaker:

• ConvertKit vs Beehiiv: choose ConvertKit for automation; choose Beehiiv for growth.
• Beehiiv vs Substack: choose Beehiiv for building a business; choose Substack for staying focused on writing.
• ConvertKit vs Substack: choose ConvertKit for control; choose Substack for simplicity.

Those are the key differences in one line.

Final opinion

If a friend asked me today which newsletter platform they should choose, I would not give one universal answer.

But I would say this:

Beehiiv is the most compelling all-around choice for a newsletter business. If you know you want growth, monetization options, and a platform that treats your newsletter like a serious publication, it’s probably the strongest default right now. ConvertKit is still the best choice for creator-led email businesses. If your newsletter is tied to products, funnels, and segmented audience journeys, it’s the most useful tool of the three. Substack remains the best choice for writers who want to write. Not “best for everyone.” Not “best for scale.” But best for getting out of the way.

My actual stance:

• for a newsletter company, I’d pick Beehiiv
• for a creator business, I’d pick ConvertKit
• for a solo writing practice, I’d pick Substack

That’s probably less exciting than declaring one winner, but it’s more honest.

The reality is these tools are optimized for different jobs. Once you see that, the decision gets much easier.

FAQ

Is Beehiiv better than ConvertKit?

Depends what you mean by better.

Beehiiv is better for newsletter-first growth and publication-style businesses. ConvertKit is better for automation, segmentation, and creator funnels. If you’re asking which should you choose for a media-style newsletter, I’d lean Beehiiv. For a creator business, ConvertKit.

Is Substack still worth it in 2026?

Yes, if your main goal is publishing consistently and maybe charging readers. It’s still one of the easiest ways to run a paid newsletter. It’s less compelling if you need advanced email marketing or more business control.

Which platform is best for a paid newsletter?

For pure paid subscriptions, Substack is still very strong because it’s simple and proven. For a more scalable newsletter business with broader monetization, Beehiiv may be better. For paid newsletters tied to products or funnels, ConvertKit can make more sense.

Which is best for beginners?

If by beginner you mean “I just want to start writing,” Substack.

If by beginner you mean “I want to build a newsletter business properly from day one,” Beehiiv.

If by beginner you mean “I’m starting an audience around products and offers,” ConvertKit.

Can you switch later?

Yes, but I wouldn’t treat that as a casual backup plan.

You can migrate between these tools, but there’s always some friction—especially if you have automations, paid subscribers, archives, or custom signup flows. It’s worth spending an extra hour now to pick the right fit instead of assuming you’ll clean it up later.
