Part of a larger guide
This article is part of our complete guide on newsletters for companies. Start there if you want the full strategic picture.
You do not need to spend money to start a newsletter. Not in 2026.
Every major email platform offers a free plan. Some are generous. Some are bait. The difference between the two can cost you months of wasted effort and a painful migration when you hit a paywall you did not see coming.
This guide breaks down the six most relevant free newsletter tools available right now. Not a feature dump — an honest comparison with real limits, real tradeoffs, and clear recommendations based on what you are actually trying to build.
What Makes a Newsletter Tool “the Best”
Before comparing platforms, you need to know what matters. “Best” depends entirely on your situation, but five criteria separate serious tools from toys.
Free tier limits. The number that matters most is not features — it is how many subscribers you can have before paying. Some platforms cap at 500. Others let you reach 2,500. That difference determines whether you can validate your newsletter before spending a dollar.
Ease of use. If you need a YouTube tutorial to send your first email, the tool is working against you. The best platforms let you go from signup to first send in under an hour.
Integrations. Your newsletter does not exist in isolation. It connects to your website, your CRM, your analytics, your social channels. Native integrations with tools you already use save hours every week.
Growth tools. Referral programs, recommendation networks, landing pages, embeddable forms — these are the mechanisms that turn a newsletter from a broadcast into a growth engine. Some platforms include them free. Others charge extra.
Deliverability. None of the above matters if your emails land in spam. Deliverability depends on the platform’s infrastructure, sender reputation, and authentication setup. Established platforms generally perform better here, but configuration still matters.
With those criteria set, here is how the six major free tools stack up.
The Six Best Free Newsletter Tools in 2026
Mailchimp
Free plan: 500 contacts, 1,000 sends per month (daily limit of 500).
Mailchimp was once the default recommendation for anyone starting a newsletter. That era is over. After Intuit’s acquisition, the free plan was gutted repeatedly. What remains is functional but restrictive.
You get a drag-and-drop email builder, basic templates, and one audience. The editor is mature and polished — Mailchimp has been refining it for over fifteen years. You also get access to their integration ecosystem, which remains the widest in the industry. Shopify, WordPress, Squarespace, Zapier — if a tool integrates with email, it probably integrates with Mailchimp first.
Where it breaks down: The 500-contact limit is punishing. Most serious newsletters will hit that ceiling within weeks. Once you do, Mailchimp’s paid plans start at $13/month for 500 contacts — competitive, but no longer the best value. Automations are locked behind paid tiers. A/B testing is limited. And the interface, while powerful, has grown cluttered with features most newsletter creators will never use.
Pros:
- Unmatched integration ecosystem
- Mature, reliable email builder
- Strong deliverability track record
- Detailed analytics even on free plan
Cons:
- 500-contact cap makes free plan nearly unusable for growth
- Automations require paid plan
- Interface feels bloated for simple newsletters
- Pricing escalates quickly at scale
Verdict: Mailchimp is no longer the best free option. It is a good paid platform with a weak free plan. Choose it only if you need specific integrations that other platforms lack.
MailerLite
Free plan: 1,000 subscribers, 12,000 emails per month.
MailerLite is the tool we recommend most often for people starting from zero. The free plan is genuinely generous — double Mailchimp’s subscriber limit with twelve times the monthly sends. But the real advantage is what they include at no cost.
You get automations. Real ones — not watered-down sequences, but multi-step workflows with conditions and triggers. You get landing pages, pop-ups, and embedded forms. You get a website builder. You get an email editor that strikes the right balance between simplicity and flexibility.
Where it breaks down: The free plan caps at 1,000 subscribers, which is reasonable for validation but tight for growth. You lose access to the newsletter selling feature, auto-resend campaigns, and advanced reporting. The template library on free is limited compared to paid. And MailerLite’s brand is less recognized than Mailchimp’s, which occasionally matters for trust signals with enterprise clients.
Pros:
- Automations included on free plan (rare)
- Clean, intuitive interface — fast learning curve
- Landing pages and forms included free
- Best value-to-feature ratio on free tier
Cons:
- 1,000 subscriber cap still hits fast if you grow
- Limited template selection on free
- Smaller integration ecosystem than Mailchimp
- Email support only (no live chat on free)
Verdict: The best all-around free newsletter tool for most use cases. If you are starting a company newsletter and want real functionality without paying, start here.
Substack
Free plan: Unlimited subscribers, unlimited sends, free forever — until you turn on paid subscriptions.
Substack’s model is fundamentally different. You pay nothing, ever, unless you decide to charge your readers. When you do, Substack takes 10% of revenue. This means you can build a newsletter with 50,000 subscribers, send weekly for years, and never pay a cent — as long as your newsletter remains free to readers.
The platform is intentionally simple. You write. You publish. Readers subscribe. There is no drag-and-drop builder, no complex automations, no landing page generator. What you get is a clean writing experience, built-in community features (Notes, chat, comments), a recommendation network that helps you grow, and a publication page that doubles as a website.
Where it breaks down: The simplicity is also the limitation. You cannot build complex email sequences. You cannot create custom templates that match your brand identity. Analytics are basic. There is no native CRM integration. If you need your newsletter to feed into a larger marketing stack, Substack will frustrate you.
The 10% revenue cut also stings at scale. A newsletter earning $10,000/month pays $1,000 to Substack — plus Stripe’s processing fees. At that level, Ghost or Beehiiv’s paid plans are dramatically cheaper.
Pros:
- Truly unlimited free plan (no subscriber cap)
- Built-in community and recommendation network
- Zero configuration needed — write and send
- Growing discovery features help new newsletters get found
Cons:
- Minimal design customization
- No automations or advanced segmentation
- 10% cut on paid subscriptions adds up fast
- Limited integration options
- You are building on Substack’s platform, not your own
Verdict: Ideal for founders and thought leaders who want to publish consistently with zero friction. Not suitable for companies that need brand control or marketing automation.
Beehiiv
Free plan: 2,500 subscribers, unlimited sends.
Beehiiv entered the market in 2022 built specifically for newsletter operators, and it shows. The free plan is the most generous on this list by subscriber count, and it includes features that competitors lock behind paywalls.
On the free tier you get a website, custom landing pages, audience segmentation, and — critically — referral programs and recommendation network access. These growth tools are what set Beehiiv apart. The referral program lets you incentivize existing subscribers to share your newsletter, creating organic growth loops that other free platforms simply do not offer.
The editor is modern and fast. Analytics are detailed. The overall experience feels like a platform designed in 2024, not one dragging legacy decisions from 2010.
Where it breaks down: The free plan does not include automations or A/B testing. You get Beehiiv branding on your emails and website. Custom domains require the paid plan ($39/month). The platform is newer, so the integration ecosystem is still growing — you will not find the depth of Zapier connections that Mailchimp offers.
Pros:
- Highest free subscriber cap (2,500)
- Referral program included free
- Recommendation network for organic growth
- Modern, newsletter-first design
- Unlimited sends on free plan
Cons:
- No automations on free plan
- Beehiiv branding on free tier
- Custom domains require paid plan
- Younger platform — fewer integrations
- Paid plans jump to $39/month
Verdict: The best choice if growth is your primary goal. No other free plan gives you 2,500 subscribers plus referral tools. Ideal for content-focused newsletters that want to scale before spending.
ConvertKit (Kit)
Free plan: 1,000 subscribers, unlimited sends, unlimited landing pages and forms.
ConvertKit — now rebranded as Kit — built its reputation serving professional creators. The free plan reflects that focus: you get landing pages, forms, and basic email broadcasts for up to 1,000 subscribers.
The platform excels at tagging and segmentation. Even on the free plan, you can tag subscribers based on behavior and interests, creating a foundation for targeted messaging as you grow. The landing page builder is one of the best available at any price point — clean templates, fast loading, high conversion rates.
Where it breaks down: The free plan does not include automations or sequences. You can send broadcasts, but you cannot build automated welcome series, drip campaigns, or behavioral triggers. That is a significant limitation for company newsletters that need onboarding flows. Visual automations — Kit’s strongest feature — require the $25/month Creator plan.
Pros:
- Excellent tagging and segmentation from day one
- High-quality landing page builder
- Clean interface focused on creators
- Strong deliverability
- Good community and educational resources
Cons:
- No automations or sequences on free plan
- Limited reporting on free tier
- Rebranding to Kit has caused some confusion
- Paid plans are pricier than MailerLite
Verdict: A strong choice for consultants and personal brands that want professional landing pages and solid subscriber management. Less suited for companies that need automation from day one.
Ghost
Free plan: Free if you self-host. Hosted plans start at $9/month.
Ghost is the outlier on this list because its free option requires technical setup. Ghost is open-source software that you can install on your own server for zero cost. If you have a developer on your team (or you are comfortable with command-line tools), you get unlimited subscribers, unlimited sends, full customization, membership features, and zero platform fees.
The hosted version — Ghost(Pro) — starts at $9/month for 500 members. Not free, but competitive, and it includes managed hosting, automatic updates, and email delivery.
Ghost’s newsletter functionality is tightly integrated with its publishing platform. You write a post, and it goes out as both a web article and an email. This makes it ideal for organizations that want their newsletter content to also function as a blog or publication.
Where it breaks down: Self-hosting requires server management — updates, security patches, email delivery configuration (usually via Mailgun). The learning curve is steeper than any other platform on this list. Theme customization requires knowledge of Handlebars templating. And if you are not technical, Ghost(Pro) at $9/month is still a cost, even if it is modest.
Pros:
- Truly free with self-hosting (no subscriber limits)
- Full ownership of your content and data
- Beautiful default themes
- Native membership and subscription features
- No platform fees on revenue
Cons:
- Self-hosting requires technical knowledge
- Smaller template and integration ecosystem
- Steeper learning curve
- Email delivery requires separate setup (Mailgun)
- Hosted plans, while affordable, are not free
Verdict: The best option for technically capable teams that want full ownership. If you have a developer, Ghost gives you more control than any other platform — for free. If you do not, look elsewhere.

Which Tool Should You Choose? It Depends on Who You Are
Stop looking for the “best” tool. Start looking for the right one for your situation.
If you are a startup founder building thought leadership alongside your product: Substack or Beehiiv. Substack if you want zero friction and built-in community. Beehiiv if you want growth tools and more control over the experience. Both let you focus on writing instead of configuring.
If you are a consultant or advisor building authority in your niche: ConvertKit (Kit) or MailerLite. Kit if landing pages and subscriber management are priorities. MailerLite if you want automations on day one — like a welcome sequence that nurtures new subscribers while you sleep.
If you are running a midsize company newsletter that needs to integrate with existing marketing infrastructure: MailerLite or Mailchimp. MailerLite for better free-tier value. Mailchimp if you already use their ecosystem or need specific ecommerce integrations. Plan to be on a paid plan quickly — company newsletters with multiple contributors and segments outgrow free tiers fast.
If you are a content creator building an audience-first business: Beehiiv. The 2,500 subscriber free cap, referral program, and recommendation network are tailor-made for audience growth. You can validate your concept and build a real subscriber base before spending anything.
The Real Limit of Free Tools
Here is the truth nobody selling newsletter platforms wants you to hear: the tool is never the bottleneck.
Every platform on this list can send an email. Every one can collect subscribers. Every one can deliver your content to an inbox. The differences are real but marginal — especially when you are under 1,000 subscribers.
The real challenge is not choosing between Mailchimp and MailerLite. It is writing something worth reading every single week.
Free tools solve the distribution problem. They do not solve the content problem. And the content problem is where 90% of company newsletters fail.
You pick a tool. You design a template. You send three issues. Then the fourth week arrives and you have nothing to say. Or you have something to say but no time to write it. Or you write something but it reads like every other corporate newsletter in your industry — safe, forgettable, and destined for the archive folder.
The platform does not fix that. A better drag-and-drop editor does not fix that. More automations do not fix that.
What fixes it is a clear editorial strategy, a consistent voice, and someone who can translate your expertise into content your audience actually wants to read.
You Have the Tool. Now You Need the Content
You can set up any platform on this list in an afternoon. The harder question is: what will you send next Tuesday? And the Tuesday after that? And every Tuesday for the next year?
At Mazkara Studio, we ghostwrite newsletters for executives and companies who know their audience deserves better than recycled blog posts and product updates. We handle strategy, writing, and editorial consistency — so you can focus on running your business while your newsletter builds authority on autopilot.
If you have the tool but not the content engine, book a 15-minute call and we will show you what a sustainable newsletter operation looks like.
You already know which platform to use. The question is whether your newsletter will be worth subscribing to — let’s make sure it is.
