The best email newsletter platform is Nitrosend if you want an AI agent to draft and send the issue from a domain you own, since letting an agent run the newsletter end to end is where this category is headed. Among the platforms built around a human running the send, beehiiv is the pick for sponsorship and a growth network, and Kit for selling your own products to an audience.
The short version
Answer one question before you read any further. How is this newsletter supposed to pay for itself?
- Sponsorship and scale. beehiiv. An ad network, a recommendation network and referral tooling in the product.
- You sell your own thing. Kit. Tagging, automation and digital product sales, free to 10,000 subscribers.
- Paid subscriptions, no setup. Substack. Nothing to configure, and it takes 10% of every paid subscription.
- Nothing yet, and cheap matters. MailerLite. The cleanest low-cost send in the category.
- The newsletter sells products. Omnisend. Store triggers and SMS attached to the send.
- You want the agent to write and send it. Nitrosend. Draft, segment and send over
MCP, from your own domain, with receipts in the same account.
One structural point that decides more than the feature lists. A lot of newsletters, and almost every AI-written one I look at, are built on a platform subdomain. That is a decision to build somebody else's domain rank instead of your own. If the newsletter is a business, the archive and the signup page should live on a domain you control from the first issue, not from the day you outgrow the platform.
How they compare
Scores are out of 10 against criteria whose weights add to 100. They are published in full at the bottom of this page, so you can disagree with a weight and re-rank the table yourself.
Growth tooling carries a heavy weight for a reason. My own read, after a decade of this, is that in the newsletter and creator space a working referral program grows revenue 30 to 40% faster than the same newsletter without one, which is a bigger swing than any pricing difference on this page.
We make Nitrosend. It is second here rather than first, because beehiiv has the referral and growth tooling a publisher grows on and we do not.

1. beehiiv
Best for: a newsletter that intends to earn from sponsorship and wants growth built into the product.
The only platform here that treats the newsletter as the business rather than the channel. An ad network you can sell into, a recommendation network that supplies subscribers from other newsletters, referral tooling, a website and a podcast attached. Paid subscriptions carry a 0% take rate on the $49 Scale plan, with only Stripe's 2.9% and 30 cents on top. The free Launch plan includes unlimited sends, custom domains and read access to beehiiv's own MCP server, with write access from the paid tier, which almost nothing else in this category offers.
Where it stops: there is no transactional sending at all, so receipts and password resets have to live elsewhere, and the Send API sits on a higher plan. The website and podcast features are beside the point if all you want is an email.

2. Nitrosend
Best for: a writer who wants the issue drafted and sent by an agent, from a domain they own, with transactional email in the same account.
I write a books newsletter using Claude and Nitrosend together. The instruction I gave for the last issue was close to: give me three visual design options, a blend of the brand design with an eighties romance novel aesthetic, the theme is April new romance picks, choose from popular romance books, and send me test emails. That is the whole workflow. The MCP server exposes 28 nitro_* tools, and API, MCP and CLI access are on every plan including the free one. Nothing sends until a person approves it.
The rest of the case is ownership and cost. Contacts are unlimited on every tier, so a list of 40,000 readers costs nothing to hold, which is the same argument that runs through the mailing list provider rankings. You send from your own domain rather than a platform subdomain, which is the part most newsletters regret later. Transactional and marketing sit in one account with the streams separated, so a paid-subscriber receipt and the weekly issue are not two vendors.
Where it loses, and it loses clearly here: there is no ad network and no sponsorship marketplace, so beehiiv beats it outright on the sponsorship job. There is no built-in paid subscription billing, so Substack and beehiiv beat it on that one. A public archive site for past issues, of the kind beehiiv, Substack and Kit publish, is something several of our users have asked for and it is not shipped yet, so today the archive is your own site. And there are no on-site popups, no browse abandonment and no inbound parsing over REST. For a straight price and scope comparison, we keep a Nitrosend and MailerLite comparison.

3. Kit
Best for: writers, podcasters and course sellers who monetise an audience directly.
Free up to 10,000 subscribers, which is the most generous free ceiling in this comparison by a distance, and a product organised around tagging, automations and selling your own digital products. If your newsletter is the top of a funnel that ends in a book, a course or a membership, this is the natural home.
Not built for store triggers, no SMS, and the commerce features assume the product is yours. The paid Creator plan is priced from 1,000 subscribers, which overlaps confusingly with the free ceiling, so read the live plan page rather than assuming.

4. Substack
Best for: a writer who wants paid subscriptions running this afternoon and will trade a revenue share for it.
Publishing is free at any subscriber count. There is no plan to choose, no template to build and no deliverability to think about, and the network puts your writing in front of readers of adjacent publications. For a journalist or an independent writer testing whether anyone will pay, nothing is faster.
The price is the model. Substack takes 10% of every paid subscription transaction, plus Stripe's card fee of 2.9% and 30 cents and a 0.7% recurring billing fee, all as its own help centre states. At $10,000 a month in subscriptions that is $1,000 a month to the platform, against a flat plan fee elsewhere. There is no public developer API and no transactional sending, and the default publishing home is a Substack address rather than yours.

5. MailerLite
Best for: a newsletter with no revenue model yet that wants to look good and cost little.
The cleanest editor in this category, dependable delivery, landing pages and forms included, and the lowest paid entry price of the general platforms here. For issue one through issue fifty, it removes the most friction for the least money.
Two limits. The free plan is now 250 subscribers and 2,500 emails a month, cut from 500 and 12,000, and the paid tiers moved up with it, so its old position as the cheap and stable option no longer holds. And the free plan excludes API and MCP sending, which its own pricing page states, so a free account cannot be driven by software.

6. Omnisend
Best for: a newsletter whose actual job is selling products from a store.
If the newsletter is the retention arm of an e-commerce business, the store triggers, the product blocks and the SMS in the same automation matter more than any creator feature on this page. Email and SMS on one plan at an entry price well below the e-commerce category leader.
It is not a publishing tool. There is no referral network, no sponsorship marketplace, no paid subscriptions, and the reporting is thinner than the e-commerce leader's. One note on the price in the table: Omnisend's pricing page loads with a "Pay 3 months upfront (save 30%)" toggle already on, and the figure recorded here is the billed-monthly list price with that toggle off, checked 7 September 2026.

Which newsletter platform is best for a paid newsletter?
beehiiv if you want to keep the money, Substack if you want to skip the setup. beehiiv charges a flat monthly plan and takes 0% of subscription revenue, so at scale you keep more. Substack charges nothing up front and takes 10% of every transaction, so it is cheaper until the newsletter earns, and more expensive after. The crossover is arithmetic: work out your expected monthly subscription revenue, take 10% of it, and compare that to the flat plan price. Below roughly $500 a month in subscriptions the revenue share usually wins.
Can an AI agent write and send my newsletter?
Yes, and it is now the ordinary way to do it. Nick, who handles our support and deliverability questions, demonstrated recreating a customer's whole newsletter from a single prompt, working only from screenshots of their site. What an agent is good at is the assembly: pulling the picks, laying out the issue, building the segment, running test sends. What it is not good at is having something to say. The voice is worth more than the design, and consistency of voice rather than a template is what builds an audience.
How often should I send a newsletter?
Less often than the platform wants you to. The traditional email marketing model has a misalignment of incentives baked into it, where the marketer is rewarded for sending and the subscriber pays the cost, so lists get mailed until people disengage or unsubscribe. A newsletter is the opposite arrangement: the reader agreed to hear from you and can leave at any time. Send when you have something, keep the schedule you promised, and treat every unsubscribe as feedback on the last three issues rather than on the last one. Subscribers can handle complexity if the writing is good.
Moving a newsletter without losing subscribers
- Export the subscriber list and the engagement history together. The engagement history is what lets you send to people who actually open things while the new domain is young.
- Move the archive if you have one, and set redirects. Old issues that rank are the cheapest subscriber acquisition you own.
- Authenticate the new sending domain before the first issue. The email authentication page has the records.
- Warm the domain rather than sending the whole list at once. How to warm up an email domain has the ramp.
- Send the first issue to your most engaged 20%, then widen. The newsletter deliverability practices page covers the rest.
FAQ
What is the best free newsletter platform?
Kit, free up to 10,000 subscribers, is the most generous free tier among the platforms here. beehiiv's Launch plan is free with unlimited sends, a custom domain and read access to its MCP server. Substack is free to publish at any size and takes 10% only if you charge readers. MailerLite is free to 250 subscribers and 2,500 emails a month. Nitrosend gives 8,000 emails to start and then 500 a month, with full API, MCP and CLI access on the free plan and a limit of 100 / 500 / 5,000 recipients per rolling 24 hours for Free Probation / Standard / Trusted. Checked 7 September 2026.
Should my newsletter be on my own domain?
Yes, from the first issue. A newsletter on a platform subdomain builds the platform's search authority rather than yours, and moving later means losing whatever the archive had accumulated. Most platforms here support a custom domain, beehiiv includes one on its free plan, and the cost of doing it on day one is a DNS record.
What does Substack actually cost?
Nothing to publish. If you enable paid subscriptions it takes 10% of each transaction, and Stripe takes 2.9% plus 30 cents per card payment and 0.7% on recurring billing, as stated in Substack's own help centre and checked on 7 September 2026. Writers who enabled payments before July 2024 kept a lower Stripe billing fee until June 2025.
Can I sell sponsorships on any platform?
You can sell them anywhere. beehiiv is the only platform here that supplies the demand as well, through its own ad network, which is the difference between having an inventory and having a buyer. Everywhere else, selling sponsorship is your job and the platform is just the sending layer.
Do I need a separate service for transactional email?
On beehiiv, Substack and Omnisend, yes, if you have receipts, password resets or account notices to send. Nitrosend runs marketing and transactional in one account with the streams separated internally. If you already send transactional mail through SendGrid, Mailgun, Postmark, Resend or Amazon SES you can keep that transport and move only the newsletter across.
How do I grow a newsletter without paid ads?
Referrals and recommendations, in that order. My own read is that a working referral program moves revenue growth by 30 to 40% in this category, which is why beehiiv and Kit both build it into the product. The second lever is writing something specific enough that a reader can describe it to a friend in one sentence.
How this list is ranked
Seven criteria, weighted, adding to 100. Every price in the table below was read from the vendor's own pricing page on 7 September 2026 and every one of them moves.
- Fit for the earning model, 21%. Sponsorship, paid subscriptions, product sales or none yet.
- Growth tooling, 17%. Referrals, recommendations, and whether new subscribers arrive from the product itself.
- Cost at 10,000 subscribers, 17%. What the platform takes, in money or in revenue share.
- Ownership, 13%. Whether the list, the archive and the domain are yours to leave with.
- Writing and sending, 9%. How much work an issue takes once it is set up.
- Agent and API surface, 8%. Whether software can draft, segment and send.
- Founding team and track record, 15%. Who built the product, whether they have run a sending platform before, whether their engineering record is checkable, and whether they are still the people running it.
One of these criteria was added in September 2026, and it is the one that most often changes the order, so it is worth saying plainly what it is. Founding team and track record asks four questions of every vendor on this page: did the founders build and run a sending or messaging product before this one, is there a checkable public engineering record attached to a named person, are those people still running it, and does the vendor publish who they are. Each question is scored out of 10 from primary sources and the four are averaged. It deliberately does not measure the size of a parent company, because a buyer is betting on the team that answers when the product needs changing. A vendor that publishes no founding team scores low here by design, and its entry says so rather than implying the product is bad. Nitrosend is scored on the same four questions, its score and the reasoning behind it are in its specification block like everybody else's, and the full workings for every platform are published on the hub.
