The best newsletter tools for a small list in 2026 are the ones with a real free tier that covers your first few hundred to few thousand subscribers without forcing you onto a paid plan: MailerLite, Beehiiv, EmailOctopus, Kit, Sender, Buttondown, and Substack all qualify. There is no single winner, because a small list has different needs than a 50,000-person operation, so this is an honest comparison of what each one is actually good at when your list is small.
I have shipped 7 iOS apps over 8 years, and every time I had a list of a few hundred early users I hit the same question: which tool is worth setting up when the list is this small? Disclosure: I build Lighthouse, which includes a newsletter, so I mention it once, honestly, near the end, and I tell you plainly where the dedicated tools win.

What a small list actually changes
When your list is under a few thousand people, the things that sell newsletter platforms to big senders barely matter. Deliverability at scale, advanced automation, AI subject-line tools, and revenue dashboards are nice, but they are not your problem yet. Your problem is getting set up fast, staying free while the list is tiny, and not having to migrate the moment you grow.
So the criteria flip. For a small list, the things that count are a generous free tier, a fast setup, a clean writing experience, and an upgrade path that does not punish you for crossing an arbitrary line. Everything else is a bonus.
For a small list, the best tool is the one you will actually send from every week, not the one with the longest feature list.
The best newsletter tools for a small list
Here are the seven tools worth considering when your list is small, and the one thing each is best at. None of them is wrong; they just suit different people.
| Tool | Best at | Watch out for |
|---|---|---|
| MailerLite | Balanced features, clean editor, automations | Free tier dropped to 500 subscribers in 2026 |
| Beehiiv | Growth tools, referrals, a recommendation network | Heavier than a small update email needs |
| EmailOctopus | Simple sends, generous free tier, low prices | Fewer growth and automation features |
| Kit (ex-ConvertKit) | Highest free subscriber ceiling, selling products | Automation is limited on the free plan |
| Sender | Big free send volume, simple setup | Smaller brand, fewer integrations |
| Buttondown | Minimalist, markdown, developer-friendly | Free covers only 100 subscribers |
| Substack | Publishing-first, zero setup, built-in discovery | Takes 10 percent of any paid subscriptions |
- MailerLite is the safe all-rounder. A clean drag and drop editor, landing pages, and real automation, even on free. The catch in 2026 is that the free plan now covers 500 subscribers rather than the 1,000 it used to, so check the current limit before you commit.
- Beehiiv is built to grow. The free Launch plan handles up to 2,500 subscribers with unlimited sends, plus a referral program and a recommendation network. If growth is the goal and you write real content, it is hard to beat.
- EmailOctopus keeps it simple and cheap. Up to 2,500 subscribers and 10,000 sends a month free, with paid tiers that stay among the lowest as you scale. A good fit if you just want to write and send.
- Kit has the most room on free. Up to 10,000 subscribers, unlimited landing pages, and the option to sell digital products. Automation is gated, but for pure capacity at zero cost nothing else comes close.
- Buttondown is for people who hate bloat. Markdown in, clean email out, free up to 100 subscribers. Perfect for a founder or developer who wants a plain update email and nothing else.
- Substack removes every decision. No setup, no cost to start, and built-in discovery, in exchange for a 10 percent cut of any paid subscriptions and very little control. Great for a writer, less so for a product newsletter you want to own.
Free tier limits compared
For a small list the free tier is the whole decision, so here are the current numbers side by side. Free plans change often, and 2026 has already moved some of them, so treat this as a starting point and confirm the live limit before you sign up.
| Tool | Free subscribers | Free monthly sends | Branding on free |
|---|---|---|---|
| Kit | 10,000 | Unlimited | Yes |
| Beehiiv | 2,500 | Unlimited | Yes |
| Sender | 2,500 | 15,000 | Yes |
| EmailOctopus | 2,500 | 10,000 | Yes |
| MailerLite | 500 | 12,000 | Yes |
| Buttondown | 100 | Generous for the size | Minimal |
| Substack | Unlimited | Unlimited | Substack branding |
On raw free capacity, Kit wins, then the 2,500-subscriber cluster of Beehiiv, Sender, and EmailOctopus, then MailerLite at 500. Substack is technically unlimited because it makes its money from paid subscriptions instead. The number that matters is the one just above where your list sits today.
Match the tool to your situation
Capacity is only half the question. The better way to choose is to start from what you are actually doing with the list.
| If you are | Reach for |
|---|---|
| A writer building an audience | Beehiiv or Substack |
| A founder sending product updates | MailerLite, EmailOctopus, or Lighthouse |
| A developer who wants no bloat | Buttondown |
| Optimising for free capacity | Kit |
| Emailing a waitlist you already collected | Lighthouse |
- Writers should pick a publishing-first tool. If the newsletter is the product, Beehiiv or Substack give you discovery, subscriber growth, and a reading experience built for content.
- Founders usually want updates, not a magazine. A product newsletter is short and occasional, so a clean, cheap sender like MailerLite or EmailOctopus is plenty, and you avoid paying for growth features you will not use.
- Where the list lives matters most. If your subscribers came from a waitlist or a signup survey, the friction is not writing the email, it is getting those people into an email tool and keeping them in sync. That is a different problem from picking the prettiest editor.
Where Lighthouse fits
If you are a content creator chasing newsletter growth, the tools above are built for you and I would point you straight at them. Lighthouse is for a narrower case: the indie founder who has already collected a small list through a waitlist or a signup survey and just wants to email those people without bolting a separate tool onto the side.
The point of having the newsletter inside Lighthouse is that the list is already there. Your waitlist signups and survey respondents are the subscribers, so there is no export, no CSV upload, and no second list to keep in sync. You write an update, segment by the answers people gave at signup, and send. It is honestly not trying to be Beehiiv; there is no recommendation network and no growth engine. It is the email half of a toolkit that also runs your waitlist and your feedback inbox, free to start, on the same data. If you would rather keep a dedicated newsletter tool you already like, that is a perfectly good choice, and the comparison above tells you which one.
Watch: a small list is an asset
Before you obsess over which sender to use, it helps to remember why the list exists at all: to learn whether the thing is worth building. Short, useful context on validating with the people you collect:
Frequently asked questions
What is the best free newsletter tool for a small list?
For pure free capacity, Kit leads at up to 10,000 subscribers, with Beehiiv, Sender, and EmailOctopus all covering 2,500. For most small lists any of these is more than enough, so the better question is which writing and growth experience you prefer, not who has the biggest free number.
How small is a small list?
In practice, anything under a few thousand subscribers behaves like a small list: every free tier covers you, deliverability at scale is not yet a concern, and your main job is to send consistently. The advice here is aimed at the first subscriber up to roughly 2,500.
Is Substack good for a small list?
Yes, if you are a writer and the newsletter itself is the product. Setup is instant and it is free until you charge, at which point Substack takes 10 percent. It is weaker if you want a product update email you fully control, or fine-grained segmentation.
Should a founder use a newsletter tool or build it into their product?
If your subscribers came from a waitlist or signup survey, keeping the newsletter on the same data avoids exporting and re-importing lists. If your list comes from elsewhere, or the newsletter is your main channel, a dedicated tool like MailerLite or Beehiiv is the simpler call.
Will I have to migrate as my list grows?
Possibly, which is why the upgrade path matters as much as the free tier. Tools like MailerLite, Beehiiv, EmailOctopus, and Kit all scale into paid plans without a forced platform change, so picking one of them early means you grow on the same tool rather than migrating mid-stream.
For a small list, stop agonising over the feature comparison and pick the tool that matches what you are doing: Beehiiv or Substack if you are building an audience, MailerLite or EmailOctopus if you are sending product updates, Kit if you want the most free room, and Buttondown if you want nothing but a clean send. The best newsletter tool for a small list is whichever one gets you writing to your people this week.
Lighthouse gives you a waitlist with survey questions, a newsletter, and a feedback inbox in one place, free to start, so the small list you collect at signup is the same list you email later, with no exporting between tools. From an indie dev, for indie devs and makers.
