Picking a newsletter platform sounds easy until you actually have to move your list, set up automations, charge for subscriptions, build landing pages, and not hate the editor six months later.
That’s where most comparisons get a little useless. They turn into feature spreadsheets and “all three are great options depending on your needs,” which is technically true and practically annoying.
The reality is these tools are built for different kinds of newsletter businesses.
If you choose the wrong one, it won’t feel wrong on day one. It’ll feel wrong later — when you want better automation, cleaner monetization, less platform dependency, or just more control over how your newsletter works.
So here’s the honest version: Substack, Beehiiv, and ConvertKit can all run a newsletter. But they do not feel the same to use, and they do not push your business in the same direction.
Quick answer
If you want the shortest possible answer to which should you choose:
- Choose Substack if you want to start writing immediately, don’t care much about customization, and like the built-in paid subscription model and discovery network.
- Choose Beehiiv if you want a modern newsletter-first platform with better growth tools, referral features, ad options, and a more “media business” feel.
- Choose ConvertKit if email is part of a broader business and you care about automations, funnels, segmentation, products, and owning your marketing stack more directly.
My blunt take:
- Best for writers and solo creators starting from zero: Substack
- Best for newsletter growth and publication-style businesses: Beehiiv
- Best for creators, coaches, startups, and businesses using email seriously: ConvertKit
If you already know you’ll need advanced automation, don’t start on Substack just because it’s easy. If you mostly want to write and publish, don’t start on ConvertKit just because it’s “more powerful.” And if your whole strategy depends on platform discovery, don’t assume Beehiiv or ConvertKit will replace what Substack’s network can do.
That’s the short version.
What actually matters
Most people compare these tools by counting features. That’s usually the wrong way to do it.
What matters is not whether each platform has forms, landing pages, or paid newsletters. They all have enough basics. The key differences are more structural.
1. What kind of business the platform wants you to build
This is the biggest difference.
- Substack wants you to build a writer-led publication inside its ecosystem.
- Beehiiv wants you to grow a newsletter media business.
- ConvertKit wants you to build a creator/business email machine.
That changes everything.
On Substack, the workflow is about publishing. On Beehiiv, it’s publishing plus growth. On ConvertKit, it’s audience management plus conversion.
In practice, this shapes how the platform feels every week.
2. How much you depend on the platform
This matters more than most people realize.
Substack is easy because it removes decisions. That’s also the trap. You get speed, but less control. Your newsletter lives in Substack’s environment, and a lot of the growth upside comes from its internal network.
Beehiiv gives you more independence while still keeping things simple. It feels more like a platform for owning your publication, not just renting space on someone else’s.
ConvertKit is the most “your business, your rules” of the three — but you pay for that with more setup and a less opinionated newsletter experience.
3. How you plan to grow
Newsletter growth can come from:
- platform discovery
- referrals
- SEO/content
- paid acquisition
- lead magnets
- funnels
- partnerships
- product ecosystem
Each tool is stronger in different areas.
Substack is strongest at native discovery and writer-to-writer recommendations.
Beehiiv is strongest at newsletter growth systems like referrals, recommendations, ad network options, and publication-oriented tools.
ConvertKit is strongest at owned growth infrastructure: forms, automations, lead magnets, sequences, and segmentation.
4. How important automation really is
A lot of people say they need automation when they really just mean “I’d like a welcome email.”
That’s not advanced automation.
If your newsletter is mainly one weekly send, plus maybe a welcome sequence, Beehiiv or even Substack may be enough.
But if you want:
- segmented onboarding
- behavior-based sequences
- product pitches
- evergreen funnels
- webinar follow-up
- subscriber tagging based on actions
then ConvertKit wins pretty clearly.
5. How you want to make money
This is where a lot of comparisons get too abstract.
There are different monetization models:
- paid subscriptions
- sponsorships/ads
- selling digital products
- selling services
- affiliate offers
- memberships/courses
Substack is built around paid subscriptions.
Beehiiv is strong for ads, sponsorships, newsletter monetization, and publication growth.
ConvertKit is strongest when email supports offers beyond the newsletter itself — courses, products, services, launches, and segmented selling.
That’s why “best for” depends heavily on your business model, not just your audience size.
Comparison table
Here’s the simple version.
| Category | Substack | Beehiiv | ConvertKit |
|---|---|---|---|
| Best for | Writers, journalists, solo creators | Newsletter operators, media-style publications | Creators, startups, businesses |
| Main strength | Easy publishing + built-in network | Growth tools + newsletter business features | Automation + segmentation |
| Setup speed | Fastest | Fast | Moderate |
| Learning curve | Very low | Low to medium | Medium |
| Paid subscriptions | Excellent | Good | Possible, but not the core strength |
| Automation | Basic | Decent, improving | Best of the three |
| Referral/growth tools | Limited compared to Beehiiv | Strong | Good, but less newsletter-native |
| Discovery/network effects | Strongest | Some | Weak native discovery |
| Customization/control | Limited | Better | Best overall control |
| Website/blog | Basic but simple | Good for newsletter sites | Fine, but not the main draw |
| Ads/sponsorship support | Limited/native ecosystem focus | Strong | Depends on your setup |
| Ownership feel | Lower | Medium-high | High |
| Best at scale? | For writer subscriptions, yes | For publication growth, yes | For business email, yes |
| Biggest downside | Platform dependence | Can feel a bit “growth-hacky” | More setup, less instant momentum |
- Substack is easiest
- Beehiiv is the most newsletter-business-focused
- ConvertKit is the most marketing-capable
Detailed comparison
Substack
Substack is still the simplest way to start a serious newsletter.
That’s its superpower.
You can create an account, write a post, enable subscriptions, and be live very quickly. The interface gets out of the way. For a lot of people, that matters more than having 30 extra features they won’t use.
I’ve seen Substack work especially well for:
- independent writers
- journalists
- commentators
- niche analysts
- essay-style creators
- people building a personal publication around a voice
It’s good when the product is the writing.
That part is worth emphasizing. If your newsletter itself is the product, Substack makes a lot of sense.
Where Substack is genuinely strong
First, paid subscriptions are native and frictionless. That matters. You don’t have to duct-tape together checkout, access, and publishing.
Second, the network effect is real. Recommendations, cross-promotion, and in-platform discovery can help. Not for everyone, and not magically — but it’s one of the few platforms where the ecosystem itself can contribute to growth.
Third, it reduces operational drag. You spend more time writing and less time setting things up.
That’s not a small thing. Plenty of newsletters die because the creator picked a system that felt “professional” but added too much complexity.
Where Substack gets limiting
The downside is control.
Customization is limited. Branding flexibility is limited. Your website experience is fine, but not especially flexible. Automation is basic. Segmentation is not where you’d want it if you run a real marketing operation.
And yes, the platform takes a cut of paid subscriptions. For some creators, that’s fair because Substack helps them start and grow. For others, especially once revenue climbs, it starts to feel expensive.
Here’s a slightly contrarian point: People often complain too much about the revenue cut and not enough about dependence on the ecosystem.
The bigger issue usually isn’t the fee. It’s that your growth model, audience habits, and publication identity can become tied to Substack’s environment.
That’s fine if you want that. It’s bad if you don’t realize you’re choosing it.
Who Substack is bad for
Substack is usually a weak fit if:
- you want sophisticated automations
- your newsletter supports a larger product funnel
- you need detailed segmentation
- your brand/site experience matters a lot
- you dislike platform dependence
A startup, SaaS company, or creator with multiple offers will usually outgrow it faster than they expect.
Beehiiv
Beehiiv sits in an interesting middle ground.
It’s not as stripped down as Substack, and it’s not as automation-heavy as ConvertKit. What it does well is give you a newsletter-native platform that is built for growth.
That sounds like marketing language, but in practice it’s true.
Beehiiv feels like it was designed by people who understand that many newsletter operators don’t just want to publish. They want to grow aggressively, run referrals, monetize through ads, optimize landing pages, and operate like a small media company.
Where Beehiiv is strongest
The growth tooling is the main appeal.
Referral systems, recommendations, audience growth mechanics, monetization options, and publication features are all more central here than in most traditional email tools.
If you’re trying to build:
- a niche business newsletter
- a media-style publication
- a daily or weekly news roundup
- a startup-focused industry letter
- a local media newsletter
- a multi-writer publication
Beehiiv makes a lot of sense.
It also gives a better ownership feel than Substack. Your publication feels more like your own property and less like a profile inside someone else’s network.
That matters for teams especially.
Where Beehiiv is weaker
Automation is the obvious limitation compared with ConvertKit.
It has enough for many newsletter operators, but if you think in terms of funnels, tags, branching logic, and offer sequences, you’ll feel the ceiling sooner.
The other trade-off is subtler: Beehiiv can push you toward growth mechanics that look impressive but don’t always create deep audience quality.
That’s my second contrarian point.
A referral program, boosted acquisition, ad monetization, and rapid list growth can all be useful. But they can also create a newsletter that looks healthier than it really is. You can end up optimizing for list size and not reader relationship.
This is not Beehiiv’s fault exactly. It’s more that the platform makes growth very available, and some operators overuse it.
In other words: Beehiiv is powerful, but it rewards people who know what kind of growth they actually want.
Best use case for Beehiiv
Beehiiv is probably the best choice if you want a newsletter-first business with:
- strong growth tools
- decent monetization options
- a more modern publication setup
- less platform lock-in than Substack
- less complexity than ConvertKit
For a lot of creators, that’s a sweet spot.
ConvertKit
ConvertKit is the most mature email marketing tool of the three for business use.
It is not the most exciting one at first glance. It’s also not the easiest to compare fairly, because it’s solving a broader problem.
Substack and Beehiiv are very newsletter-centric. ConvertKit is really about audience relationships and conversion over time.
That’s why it’s often the right choice for businesses, not just writers.
Where ConvertKit wins
Automation and segmentation are the main reasons to use it.
You can build subscriber journeys that go well beyond “person joins list, person gets newsletter.” You can tag based on behavior, run nurture sequences, separate audiences by interest, and connect email to products and offers more cleanly.
That makes a big difference if your business has:
- lead magnets
- multiple products
- coaching/services
- course launches
- webinar funnels
- evergreen sales sequences
- customer vs prospect segmentation
If the newsletter is one channel in a larger system, ConvertKit is usually the most practical option.
It also gives you more control over forms, landing pages, integrations, and overall marketing structure.
Where ConvertKit is weaker
It’s not as fun to start with.
That matters more than people admit.
Substack gives instant momentum. Beehiiv gives a modern media feel. ConvertKit can feel like you’re setting up infrastructure before you get the reward.
For some people, that’s exactly right. For others, it slows them down.
It also has weaker native discovery than Substack and less newsletter-specific growth energy than Beehiiv. You are expected to bring your own audience strategy.
That’s fine if you have one. Less fine if you’re hoping the platform itself will help create momentum.
And while ConvertKit can absolutely run a newsletter, it doesn’t always feel as editorially focused. It feels like an email business platform first.
Best use case for ConvertKit
ConvertKit is best for people who need email to do more than publish content.
That includes:
- creators selling products
- educators
- coaches
- SaaS companies
- startups building waitlists and onboarding flows
- personal brands with multiple offers
If you know your newsletter is tied to revenue operations, ConvertKit is often the safest long-term pick.
Real example
Let’s make this less abstract.
Imagine three different people launching newsletters.
Scenario 1: Solo writer building a paid analysis newsletter
Maya is a former journalist writing weekly analysis on climate policy. She wants free posts, paid subscriber-only essays, and maybe podcasts later. She doesn’t care much about fancy funnels. She wants to write, publish, and get paid.
She should probably use Substack.
Why?
Because her core product is her writing. Paid subscriptions are central. The recommendation network could help. And the simplicity means she’s more likely to publish consistently.
Could she use Beehiiv? Sure. Could she use ConvertKit? Also yes.
But both would likely add setup without improving the core business much.
Scenario 2: Small startup building an industry newsletter
A 5-person B2B SaaS startup wants a weekly newsletter in its niche. The goal is top-of-funnel growth, sponsorship potential later, and building a media asset around the company’s category. They care about landing pages, referrals, list growth, and running the newsletter like a publication.
They should probably use Beehiiv.
Why?
Because this is not just “send updates to leads.” It’s a media-style growth asset. Beehiiv matches that model better than Substack, and it’s more newsletter-native than ConvertKit for this specific use case.
The startup could still connect other tools for deeper CRM or sales workflows later.
Scenario 3: Creator with products, workshops, and funnels
Daniel teaches developers how to improve technical writing. He has a newsletter, a paid workshop, a self-paced course, free guides, and occasional cohort launches. He wants:
- welcome sequences
- interest-based segmentation
- launch emails
- behavior tracking
- different paths for free vs paid buyers
He should use ConvertKit.
This is where ConvertKit earns its keep. Daniel doesn’t just need a newsletter platform. He needs an email system that supports a business.
Substack would be too limited. Beehiiv would be better, but still not ideal if the real engine is automation and product conversion.
Common mistakes
There are a few mistakes I see over and over when people compare these platforms.
1. Choosing based on current size, not future model
A lot of people say, “I only have 300 subscribers, so I’ll just use the easiest thing.”
Maybe. But the real question is what kind of newsletter you’re building.
If you’re building a funnel-driven business, starting on Substack may create migration pain later. If you’re building a writer-led paid publication, starting on ConvertKit may create unnecessary friction now.
Your future model matters more than your current list size.
2. Overvaluing features you won’t use
People love saying they want advanced automation.
Most won’t build it.
If you’re realistically going to send one weekly email and a simple welcome sequence, don’t choose a platform mainly because it can do complex branching logic.
The reverse is also true: don’t dismiss automation if your business genuinely depends on it.
3. Assuming growth tools automatically mean quality growth
This one matters a lot with Beehiiv-style comparisons.
More growth mechanics do not guarantee better readers. If your acquisition channels are weak, no platform will save you.
Sometimes slower organic growth with the right audience beats a fast-growing list full of low-intent subscribers.
4. Underestimating migration pain
Moving a newsletter later is possible. It’s not always fun.
Templates, domains, automations, archives, subscriber preferences, paid members, and analytics continuity all get messy.
So yes, you can switch later. But “I’ll just migrate if needed” is often said too casually.
5. Thinking Substack is only for beginners
This is a mistake in the other direction.
Substack is simple, but simple doesn’t mean unserious. There are plenty of high-quality paid publications on it making real money.
The issue is not whether Substack is “pro.” The issue is whether its model fits yours.
Who should choose what
Here’s the clearest guidance I can give.
Choose Substack if:
- your main job is writing
- the newsletter itself is the product
- you want paid subscriptions built in
- you value speed and simplicity over control
- you want access to a writer/discovery ecosystem
- you are a solo creator who doesn’t want to manage much tech
Substack is best for independent writers, analysts, journalists, and opinion-led publications.
Choose Beehiiv if:
- you want to grow a newsletter aggressively
- you care about referral systems and publication features
- you want monetization options beyond just paid subscriptions
- you’re building a media-style newsletter business
- you want more ownership and flexibility than Substack
- you don’t need deep automation like a full marketing platform
Beehiiv is best for startups, operators, niche media brands, and newsletter-first businesses.
Choose ConvertKit if:
- your newsletter supports a broader business
- you need automations, segments, and funnels
- you sell products, services, courses, or memberships
- you care about subscriber journeys, not just broadcasts
- you want more control over your marketing stack
- you’re okay trading simplicity for capability
ConvertKit is best for creators with offers, educators, coaches, startups, and businesses that take email seriously.
Final opinion
If I had to simplify the whole comparison into one sentence:
- Substack is for publishing
- Beehiiv is for newsletter growth
- ConvertKit is for email marketing with a newsletter attached
That’s a little reductive, but mostly true.
My personal stance:
If you’re a writer starting a publication from scratch, I’d lean Substack unless you already know you’ll hate platform dependence.
If you’re building a serious newsletter business and growth is central, I’d lean Beehiiv. For a lot of modern operators, it’s the most balanced option.
If your newsletter is tied to products, funnels, or customer journeys, I’d choose ConvertKit and not overthink it.
And if you’re stuck between all three, here’s the tie-breaker:
- Choose Substack if you want the least friction
- Choose Beehiiv if you want the best newsletter-first growth setup
- Choose ConvertKit if you want the strongest long-term business infrastructure
That’s really the answer to which should you choose.
FAQ
Is Substack better than Beehiiv?
Not generally — just for different things.
Substack is better if you want a simple writing and subscription experience with built-in discovery. Beehiiv is better if you want stronger growth tools, more publication control, and a more independent newsletter business setup.
Is Beehiiv better than ConvertKit?
If your newsletter is the business, often yes.
If your newsletter is part of a bigger creator or company funnel, not necessarily. ConvertKit is stronger on automation, segmentation, and running email as a business system.
Which is best for paid newsletters?
For pure paid newsletters, Substack is still one of the easiest and cleanest options.
Beehiiv also works well, especially if you want broader newsletter growth and monetization options. ConvertKit can support paid products, but it’s usually not the first tool I’d pick for a paid editorial newsletter specifically.
Which platform is best for startups?
Depends on the startup.
If the startup wants to build a category newsletter or media asset, Beehiiv is often the best fit. If it needs lifecycle email, onboarding, lead nurturing, and product-related automation, ConvertKit is usually better.
Substack is less often the right answer for startups unless the brand is very founder-led and editorial.
Can you switch later?
Yes, but don’t treat that as painless.
You can migrate subscribers and content, but there’s usually friction around automations, archives, paid members, templates, analytics, and domain setup. It’s better to choose based on your likely 12–24 month direction, not just what feels easiest today.
