Best newsletter platforms for writers (2026): What ChatGPT, Claude & Gemini Recommend

Substack is the newsletter platform AI models name most for writers. It was named in 50 of 50 recorded answers and came first in 32 of 50. Beehiiv, Ghost and Kit follow, each named in most answers. Newsletter platforms here means the tools a writer uses to publish and send a newsletter, from writer-first publishing platforms to general email marketing software. The ranking counts which products 10 AI models, including ChatGPT, Claude and Gemini, name when a writer asks. It does not rate the products.

TL;DR

• Starting with no readers: pick Substack. Every model names it, and it comes first in most answers to the prompts that mention a writer.
• Building a paid newsletter business: shortlist Beehiiv. It is the one product that regularly takes first place from Substack, mostly when the prompt stops mentioning a writer.
• Owning the site and the list: look at Ghost. It is in 48 of 50 answers, yet only OpenAI models ever put it first.
• Selling books, courses or downloads: Kit is the fit the models describe, though no answer names it first.
• Below Kit, presence drops under half the answers. MailerLite is the budget pick the author guides favour. ActiveCampaign, Brevo and Klaviyo surface only when a model is asked for a neutral comparison.

1. Substack

Pick Substack if you are starting with no readers and want the platform itself to help people find you.

Measured: named 50 of 50 (Substack 100%), first 32 of 50 (Substack 64%), average position 1.44.

Most answers use Substack as the reference point and argue every other product against it. ChatGPT opens its answer to the first prompt with “Best overall for most independent writers: Substack.” The captured video describes Substack as a platform for writers first and internet marketers second. Jane Friedman says Substack is most popular with journalists, freelancers and others who think they might charge for their newsletter in the future. The weak spot is growth from a standing start. The video says discovery is a little uneven for a brand new Substack. Its first places cluster in the prompts that mention a writer. It loses first place most often when a model is asked for a neutral comparison.

Pros

• In all 50 answers, across all four model families
• Each post is sent as an email and published on your website
• You own the list and can move it to another platform

Cons

• Minimal customisation and no marketing automations, in the video’s summary
• A custom domain costs a one-time fee

Pricing: a completely free platform that makes money by charging transaction fees on paying subscribers.

Best for: writers starting without an audience who want discovery built in.

2. Beehiiv

Pick Beehiiv if the newsletter is meant to earn money and you want growth and monetisation tools on the same platform.

Measured: named 49 of 50 (Beehiiv 98%), first 15 of 50 (Beehiiv 30%), average position 1.88.

Beehiiv is the one product that regularly takes first place from Substack, and where it does so shows what the models think it is for. Most of its first places come from the neutral comparison prompt and the paid-newsletter prompt. Perplexity’s paid-newsletter answer reads: “For a paid newsletter, the best default choice is usually Beehiiv if you want the strongest mix of monetization, growth tools, and control over revenue.” Beehiiv tops the captured video’s list because of a very generous free plan. On that free plan, monetisation options are locked. The models also cited Beehiiv’s own site, beehiiv.com, 112 times in this category, more than any other host.

Pros

• Nine of the ten models include it in all five answers
• Second only to Substack on first places, at 15 of 50
• Unlimited email sends, a custom website and analytics on the free Launch plan
• Paid subscriptions carry no transaction fee once you upgrade

Cons

• Automations such as a welcome sequence need a paid plan
• Beehiiv websites are a bit cookie-cutter, in the reviewer’s opinion
• Beehiiv 93.3% in the OpenAI family, its lowest family share

Pricing: free Launch plan, with monetisation tools unlocked when you upgrade.

Best for: a paid newsletter run as a business.

3. Ghost

Pick Ghost if you already have readers and want to own the website, the brand and the subscriber list.

Measured: named 48 of 50 (Ghost 96%), first 3 of 50 (Ghost 6%), average position 3.08.

The models include Ghost almost everywhere and lead with it almost nowhere. All three of its first places come from OpenAI models answering a prompt about a writer. Each of those answers makes ownership the deciding factor. GPT-5.6 Luna puts it this way: “Ghost is my default recommendation for a writer who wants a polished website, newsletter, memberships, and long-term ownership of their brand.” Other answers attach a condition. Gemini 3.5 Flash warns that Ghost brings no built-in discovery. Claude Opus 5 advises a writer with no audience to start on Substack, and a writer with an existing following to go to Beehiiv or Ghost. None of the three captured guides covers Ghost, so its record here comes from the answers alone.

Pros

• Eight of the ten models name it in all five answers
• Ghost 100% in both the OpenAI and Anthropic families
• The only product besides Substack and Beehiiv ever named first

Cons

• First in 3 of 50 answers, the widest named-to-first gap in the sample
• Gemini 3.5 Flash and Sonar Reasoning Pro each leave it out of one answer
• No public pricing is recorded in the captured pages

Pricing: no public pricing is recorded in the captured pages. ChatGPT and GPT-5.6 Luna describe paid hosted plans with no platform fee on paid subscriptions.

Best for: writers with an existing audience who want full ownership.

4. Kit

Pick Kit if the newsletter is one part of a creator business that sells books, courses or digital products.

Measured: named 44 of 50 (Kit 88%), first 0 of 50 (Kit 0%), average position 3.59.

Kit, the former ConvertKit, is the most-named product in the sample that no answer puts first. The recorded answers give it a fixed role. GPT-5.6 Sol lists it for creators selling courses, products, coaching or memberships. Sonar Reasoning Pro calls it the fit for writers who also sell other digital products. The captured video backs that role. It says Kit lets you sell digital products and run paid newsletters with no transaction fees. Jane Friedman uses Kit for her free newsletters. Pauline Wiles finds the ConvertKit paid plans rather expensive for what you get. A writer with nothing to sell gets little from that role, which fits the models never leading with it.

Pros

• Seven models name it in all five of their answers
• Unlimited email broadcasts on the free newsletter plan
• Kit 100% in the OpenAI and Google families

Cons

• Sales pages pretty basic, according to the video
• Claude Opus 5 includes it in just 2 of 5 answers

Pricing: free newsletter plan, with advanced email sequences and Kit branding removal on the paid Creator plan.

Best for: writers who sell courses or digital products beside the newsletter.

5. MailerLite

Pick MailerLite if budget comes first and you want automations and a simple website on a free plan.

Measured: named 22 of 50 (MailerLite 44%), first 0 of 50 (MailerLite 0%), average position 5.14.

MailerLite is where the author guides and the models part ways. Jane Friedman calls MailerLite the more economical choice, and the one favored by authors. Pauline Wiles names MailerLite the best free newsletter service. She states that she is not a MailerLite affiliate. The models are less sure. They name it in fewer than half their answers, and their counts vary more by model than for any product ranked above it. A buyer who asks a single model can come away with a very different picture of MailerLite, depending on which model it is.

Pros

• Email automation builder, websites and landing pages on the free plan
• All five Perplexity answers include it

Cons

• Never placed first in any of its 22 appearances
• Just one mention each from GPT-5.6 Sol, GPT-5.6 Luna and Gemini 3.5 Flash
• Ruled out by Pauline Wiles for her own list because an integration she needs was too clunky

Pricing: free plan, then paid plans the video calls quite cost-effective against the industry leaders.

Best for: authors who want free automations on a free plan.

6. Buttondown

Pick Buttondown if you want an independent tool that does one job, sending the newsletter.

Measured: named 17 of 50 (Buttondown 34%), first 0 of 50 (Buttondown 0%), average position 5.35.

Jane Friedman lists Buttondown among some of the most popular newsletter services. She calls it a choice for those who want to avoid the corporately owned newsletter services. The models describe the same product. Claude Opus 5 calls it minimalist and privacy-focused, with a markdown editor. Gemini 3.5 Flash presents it as an independent favourite with a lightweight markdown editor. Its mentions follow the prompt. The models offer it to a writer who wants a simple tool, and leave it out when the question turns to a subscription business.

Pros

• Keeps the focus on email newsletter delivery, in Jane Friedman’s account
• Claude and Claude Opus 5 each include it in 3 of 5 answers
• Mentioned at least once by nine of the ten models

Cons

• Zero of five Perplexity answers mention it
• Missing from every answer to the paid-newsletter prompt
• None of the captured guides records a price

Pricing: no public pricing is recorded.

Best for: writers who want a simple, independent tool for sending email.

7. Mailchimp

Pick Mailchimp only if the newsletter is one part of wider business email marketing, such as an online store.

Measured: named 10 of 50 (Mailchimp 20%), first 0 of 50 (Mailchimp 0%), average position 6.3.

Mailchimp appears in the answers as a business email tool a writer could use, not as a writer’s platform. Perplexity frames it for broader business use. GPT-5.6 Sol lists it for conventional business email marketing. The captured video calls Mailchimp a very powerful email marketing tool, particularly for e-commerce. Jane Friedman uses MailChimp for her paid newsletter. The model spread is thin and even, with most models naming it in one of five answers. That pattern reads as a product the models list for completeness, and it matches the business framing in the answers that do explain it.

Pros

• Mentioned by nine of the ten models
• Sonar Reasoning Pro names it in 2 of 5 answers, its highest count from any model

Cons

• Free plan described as more of a free trial
• Very popular but not easy to use, in Pauline Wiles’s experience
• No first placement in 10 appearances

Pricing: a free plan with no branding removal and no marketing automations, then paid plans.

Best for: businesses, especially online stores, that send a newsletter beside other email marketing.

8. ActiveCampaign

Pick ActiveCampaign only if the newsletter feeds a business that runs complex automation sequences.

Measured: named 4 of 50 (ActiveCampaign 8%), first 0 of 50 (ActiveCampaign 0%), average position 6.75.

Every ActiveCampaign mention comes from one prompt, the neutral request to compare the top newsletter platform options. None of the prompts that mention a writer or a paid newsletter produced it. Claude Fable 5 lists it for complex business-to-business automation sequences. Claude Opus 5 groups it with the tools built for businesses running campaigns and CRM workflows, and separates those from the newsletter platforms built for creators. No captured guide covers ActiveCampaign. For a writer who only needs to publish and send, the answers give no reason to shortlist it.

Pros

• Four separate models name it once each
• Claude Fable 5’s pick for complex automation sequences

Cons

• No OpenAI model names it
• Pricing absent from every captured page

Pricing: no public pricing is recorded.

Best for: businesses running complex automation sequences, as Claude Fable 5 frames it.

9. Brevo

Pick Brevo if you send an occasional newsletter to a large list and cost per send matters more than publishing features.

Measured: named 4 of 50 (Brevo 8%), first 0 of 50 (Brevo 0%), average position 7.25.

Brevo, like ActiveCampaign, appears only in answers to the comparison prompt. Claude Opus 5 places it with the campaign and CRM tools. The captured video treats Brevo as a sending tool. It says Brevo can email a massive list for cheap. It calls Brevo probably the most cost-effective option for a monthly newsletter. That is a narrow job. The models reach for Brevo only when the question stops being about a writer, and the video frames it around list size and send cost. A writer who publishes often, or wants a hosted newsletter site, is outside the use both describe.

Pros

• Email and SMS campaigns on the free plan
• Real-time event triggers in free-plan automation
• Three Anthropic models name it once each

Cons

• OpenAI and Google models never name it
• Average position 7.25, the lowest placing of any product in the sample

Pricing: a free plan with a daily email limit, then a paid Starter plan.

Best for: a monthly newsletter sent to a large list.

10. Klaviyo

Pick Klaviyo only if you run an online store and the newsletter is part of its e-commerce marketing.

Measured: named 1 of 50 (Klaviyo 2%), first 0 of 50 (Klaviyo 0%), average position 7.

Claude Fable 5 lists Klaviyo in its comparison answer under specialised picks, as another strong e-commerce option. That is its only mention in the sample, and no captured guide covers it. The single mention places Klaviyo outside the newsletter category as the models describe it. A writer weighing Klaviyo is choosing a store-marketing tool, and the useful comparison is with other e-commerce email tools. It makes the list because the panel counts any name, and Loops, Resend, Paved and Medium drew none.

Pros

• Claude Fable 5 lists it as a strong e-commerce option
• Named at least once, unlike Loops, Resend, Paved and Medium

Cons

• Nine of the ten models never mention it
• No price on record in any captured page

Pricing: no public pricing is recorded.

Best for: online stores running e-commerce email.

How the tools compare

Answer share is the share of the 50 answers that named the product. First share is the share where it appeared before any other tracked product. Substack leads on both. Beehiiv and Ghost nearly match it on presence, and only Beehiiv takes a real share of first places. Kit forms a band of its own, present in most answers and first in none. From MailerLite down, each product appears in fewer than half the answers and none is ever named first. Every recorded answer sits in the newsletter platforms category record.

Where do the models disagree?

They agree on the leader and split below Kit. All ten models named Substack in all five answers, and every model family has Substack as its leader.

Kit is the first break. Claude Opus 5 names it in 2 of 5 answers and Sonar Reasoning Pro in 3 of 5. That leaves Kit 80% in the Anthropic family, against Kit 100% for OpenAI and Google.

MailerLite is the sharpest split. Perplexity named it in all five answers, while GPT-5.6 Sol, GPT-5.6 Luna and Gemini 3.5 Flash named it once each. By family, that is MailerLite 70% for Perplexity, against MailerLite 33.3% for OpenAI and MailerLite 30% for Google.

Buttondown runs the other way. Perplexity never named it, while Claude and Claude Opus 5 named it in 3 of 5.

At the bottom, Gemini never named Mailchimp. ActiveCampaign, Brevo and Klaviyo never came from an OpenAI model. Claude Fable 5 is the only model that named all three.

Why does the question decide which platform comes first?

The models read “writer” as someone starting with no audience, and they put the tool built for that writer first. The five prompts split into two kinds, and the order of names changes between them.

Three prompts mention a writer. In those answers Substack comes first in most cases. Ghost takes all three of its first places there, each from an OpenAI model that treats ownership as the priority. Gemini, answering the paid-newsletter prompt, states the assumption behind that order: “Substack remains the go-to platform for writers launching a new publication without an existing audience.”

The other two prompts drop the writer. “Compare the top newsletter platform options right now.” produces a different list. Beehiiv comes first in most of those answers, and that prompt alone brings in ActiveCampaign, Brevo and Klaviyo. The paid-newsletter prompt sits between the two. GPT-5.6 Sol, GPT-5.6 Luna, Perplexity and Sonar Reasoning Pro put Beehiiv first there, and the other models keep Substack first.

Being named first is still not the same as being recommended. Claude Opus 5 names Beehiiv first in answers that open with a warning about the sources. One reads: “most ‘best newsletter platform’ roundups run affiliate programs, and beehiiv’s is unusually generous.” The count records Beehiiv first in those answers, even though the sentence is a caution.

The table cannot show any of this. It adds all five prompts together. So the order at the top of the list is the order for a writer with no audience, because that is the reader most answers assume. A writer who already has readers, or who asks about a paid product, gets a different first name.

How the sample was built

10 models x 5 fixed prompts = 50 recorded answers. Each model answered each prompt once, in edition 2026-09. The five prompts, verbatim:

1. “What is the best newsletter platform for a writer? Name specific products.”
2. “Which newsletter platform would you recommend to a writer in 2026?”
3. “Compare the top newsletter platform options right now.”
4. “I’m a writer and I need a newsletter platform. What should I use and why?”
5. “Best newsletter platform for a paid newsletter?”

The models come from four families. OpenAI supplied 15 answers, from GPT-5.6 Sol, ChatGPT and GPT-5.6 Luna. Anthropic supplied 15, from Claude Opus 5, Claude and Claude Fable 5. Google supplied 10, from Gemini and Gemini 3.5 Flash. Perplexity supplied 10, from Perplexity and Sonar Reasoning Pro.

The panel tracked 14 vendors in this category, and 10 were named. Loops, Resend, Paved and Medium were tracked and never named, so they carry no row. The method page sets out how answers are recorded and counted.

How this sits against the newsletter platform guides

The captured Google results for this question are guides, videos and forum threads. Three pages were read in full. A Reddit thread and a Facebook group post refused the fetch and are not described here.

David Utke’s video ranks free email newsletter plans. His top picks are Beehiiv and Kit. The video says it uses affiliate links. It also covers Sender and Jetpack, which the panel does not track.

Pauline Wiles’s guide at Brilliant Author compares Squarespace, ConvertKit, Mailchimp and MailerLite for authors. The page states that it contains affiliate links. She is a Squarespace affiliate and a ConvertKit affiliate. Its comparison table carries its own research date, older than the article, with Substack added in a later update.

Jane Friedman’s guide is mostly strategy: frequency, content, sign-up forms and list growth. It names MailerLite, Substack, Kit and Buttondown among the most popular services.

Those guides rank products for purchase, from each author’s own use. The list here counts the names that 50 AI answers produce, and the gaps between the two are useful. Ghost, named in 48 of 50 answers, appears in none of the three guides. Beehiiv appears in one. The per-model split and the prompt-by-prompt order exist in none of them. Two roundup sites in the same Google results, sequenzy.com and skrapp.io, are also among the hosts the models cited most, with 65 and 31 citations. Search results and AI answers draw on overlapping material.

What should a writer do with this?

Match your situation to the condition the models attach, then check the vendor.

With no audience yet, start with Substack. It is the default the whole panel gives that writer.

With existing readers, or with subscription revenue in view, shortlist Beehiiv and Ghost. Beehiiv is the growth and monetisation pick. Ghost is the ownership pick.

If you sell courses or digital products, look at Kit. On a tight budget with automations in mind, look at MailerLite.

Then confirm the current price on the vendor’s own site. The captured video warns that it is accurate as of its posting date and may not be accurate in the future. When you ask a model yourself, say whether you already have readers and whether you plan to charge. The order you get back depends on it.

What these counts cannot tell you

These counts measure presence in AI answers. They say nothing about uptime, deliverability, support, pricing fairness or fit with your stack. Being named differs from being recommended, because an answer can list a product only to warn against it. Each model answered each prompt once, so a single answer moves a count by one. The figures are one dated snapshot, edition 2026-09, and a later edition can differ. Names are matched as strings, so an answer that says ConvertKit counts for Kit. The answers came through model APIs, which can differ from consumer chat apps, and all five prompts were in English.

Frequently asked questions

What is the best newsletter platform for writers?

By AI answer count, Substack. Every model named it in every answer. The more useful question is which situation you are in. The models point a writer with no audience to Substack, a newsletter business to Beehiiv, an ownership-first writer to Ghost and a writer who sells products to Kit. The counts show how often models name each product, not which one performs better.

What is the best platform to create a newsletter?

The right tool depends on what the newsletter must do besides send email. Jane Friedman says that, aside from your own website, the only tool you need is a formal email newsletter service. That service automates the subscription process, stores subscriber addresses and archives newsletter issues. Substack, Beehiiv and Ghost also give a writer a hosted site, and the models name all three in almost every answer.

Is there a better option than Mailchimp?

For a writer, six products are named more often than Mailchimp. Substack, Beehiiv, Ghost, Kit, MailerLite and Buttondown all appear in more answers, and Mailchimp is never named first. Pauline Wiles advises looking elsewhere if you want a welcome sequence or a consistent, intuitive interface. More often named is not the same as better built.

How to create a newsletter for authors?

Start with a home for sign-ups, then choose the service. Jane Friedman says it is best to have your own website or blog before you start building a list. She calls a sign-up form on your website an essential marketing strategy. Pauline Wiles encourages deciding on your website platform before, or at the same time as, the email provider. Jane Friedman also advises deciding on your frequency and sticking with it.

Does Substack take a cut of paid subscriptions?

Yes. The captured video says Substack takes a transaction fee on top of Stripe’s fees. It also says Substack is a completely free platform that makes money when you make money. The same video says Beehiiv takes no transaction fee on paid subscriptions once you upgrade.

Why are Medium and Loops not on this list?

The panel tracked them and no model named them. Loops, Resend, Paved and Medium appeared in none of the 50 answers. A product no model names is not listed and gets no share.

Can a vendor pay to rank higher on this list?

No. Positions are not sold, sponsored or influenced. Vendors cannot pay to appear, be reordered or be removed. The order is the measured count, and every recorded answer sits in the category record.
