The best free newsletter platform depends on your goal: audience growth, paid subscriptions, or reliable email marketing. For most independent publishers, Substack and beehiiv are the easiest starts. For small businesses, MailerLite and Brevo usually offer better control. If you care about clean writing, basic analytics, and fast publishing, do not overbuild your setup on day one.
TLDR: Use Substack if you want the simplest free publishing tool with built-in discovery and paid newsletter options. Use beehiiv if growth tools, referral programs, and newsletter-style publishing matter more. A solo consultant with 800 subscribers, a 42% open rate, and two sponsor mentions per month may outgrow a basic tool fast, so analytics and export options matter. For a local business sending 1,200 emails per month, MailerLite or Brevo may be more practical than creator-first platforms.
What makes a free newsletter platform worth using?
A good free newsletter platform should let you publish without friction, collect subscribers safely, and understand what readers do after they receive an email. That sounds obvious. Yet many tools hide basic features behind paid plans, cap your sends, or make list exports unnecessarily annoying.
Before choosing, check these points:
- Subscriber limits: Some free plans allow many contacts. Others stop at a few hundred.
- Email send limits: A platform may allow 1,000 contacts but only a small number of monthly sends.
- Analytics: Open rates, click rates, unsubscribes, and growth sources should be easy to find.
- Customization: Forms, landing pages, domains, and templates matter more as your list grows.
- Monetization: Paid subscriptions, sponsorship tools, and referral systems are useful for creators.
- Data ownership: You should be able to export subscribers without begging support.
Best free newsletter platforms to consider
1. Substack: Best for writers who want to publish fast
Substack is the cleanest choice for writers, analysts, educators, and commentators who want to start immediately. You can publish posts, send emails, host a public archive, and offer paid subscriptions. There is no complex campaign builder to set up. That is the point.
The free plan is attractive because Substack generally does not charge until you earn money from paid subscriptions. When you do, it takes a percentage of revenue, with payment processing fees added separately. This model works well if you want to test demand before paying monthly software fees.
Best for: solo writers, journalists, essayists, niche analysts, and creators testing paid content.
Weak point: Design control is limited. Honestly, it feels like every Substack has the same bones, even when the writing is strong.
2. beehiiv: Best for audience growth
beehiiv is built for newsletter operators who care about growth. It offers a modern editor, public newsletter pages, audience analytics, and tools aimed at referrals and monetization. The free plan is often generous enough for early-stage publishers, though some of the best growth features sit on paid tiers.
What makes beehiiv stand out is its focus on newsletter mechanics, not general email marketing. You can track subscriber sources, publish web posts, and build a media-style newsletter with less technical work.
Best for: creators, startup newsletters, media projects, and operators who plan to scale.
Weak point: Expect to waste time checking which useful feature is free and which one needs an upgrade. The line can feel frustrating when growth starts working.
3. MailerLite: Best free option for small businesses
MailerLite is a strong choice for businesses that need newsletters, landing pages, signup forms, and basic automation. Its free plan is commonly useful for small lists, especially if you send a predictable number of emails each month.
It is less “creator culture” and more practical email marketing. That can be a good thing. A bakery, accountant, fitness coach, or local retailer may need simple campaigns and reliable forms, not a social publishing network.
Best for: small businesses, service providers, coaches, and ecommerce beginners.
Weak point: Some templates and advanced tools require payment. The interface is clear, but approvals and account checks can slow setup if your business category triggers review.
4. Brevo: Best when send limits matter more than contact limits
Brevo, formerly Sendinblue, is useful if you want email marketing plus CRM-style tools. Its free plan has often focused on daily email sends rather than tight contact limits. That can be helpful if your list is large but you send less often.
Brevo also supports transactional email, SMS features, and sales tools. That makes it broader than a pure newsletter platform. For some teams, that is useful. For a solo writer, it may feel heavier than needed.
Best for: small companies, nonprofits, sales teams, and businesses with mixed email needs.
Weak point: The publishing experience is not as smooth as Substack or beehiiv. It is built for campaigns, not for writing essays.
5. Mailchimp: Best known, but not always best value
Mailchimp remains one of the most recognized email platforms. It offers templates, signup forms, audience tools, and broad integrations. For a very small list, it can be enough.
The problem is that Mailchimp’s free plan has become more limited over time. Contact and send caps may feel tight sooner than expected. The product also includes many features you may not need if your only goal is publishing a serious newsletter.
Best for: beginners who want a familiar brand and simple email campaigns.
Weak point: Pricing can rise quickly as contacts grow. It drives me crazy that a simple list can become expensive before the newsletter earns real money.
6. Kit: Best for creators who sell products
Kit, previously known as ConvertKit, is popular with creators who sell courses, downloads, coaching, or memberships. It is stronger than basic newsletter tools when you need tags, sequences, and creator commerce features.
The free plan can be useful if you are building an audience before launching a product. Its automation and segmentation options become more valuable once readers start taking different actions, such as downloading a guide or joining a waitlist.
Best for: course creators, coaches, digital product sellers, and creators building sales funnels.
Weak point: For pure writing, it can feel like too much system. You may spend more time organizing tags than improving the newsletter.

How to choose the right free platform
If you are starting from zero, pick for the next six months, not the next six years. A free tool should help you publish consistently and collect reader signals. It should not force you into hours of setup before your first issue.
Use this simple guide:
- Choose Substack if your main asset is writing and you want paid subscriptions later.
- Choose beehiiv if you want a newsletter brand with growth tracking and referral potential.
- Choose MailerLite if you run a small business and need forms, landing pages, and campaigns.
- Choose Brevo if you need email plus CRM or transactional features.
- Choose Kit if your newsletter supports products, courses, or coaching.
- Choose Mailchimp only if its current free limits fit your list and send volume.
Key metrics to track from day one
Do not obsess over every number. Track a few that show reader trust.
- Subscriber growth: A new newsletter gaining 5% to 10% subscribers per month is building momentum.
- Open rate: Many healthy niche newsletters sit around 35% to 50%, though results vary by topic.
- Click rate: A 2% to 5% click rate can be solid for general newsletters. Highly engaged lists may do better.
- Unsubscribe rate: If more than 0.5% unsubscribe per send, review your promise, frequency, or targeting.
- Source quality: Track whether readers come from search, referrals, social posts, or recommendations.
Final recommendation
For most writers and creators, Substack is the safest free starting point because it removes technical friction. For serious audience growth, beehiiv is the stronger long-term bet. For businesses, MailerLite and Brevo offer more practical marketing control.
Choose the platform that matches your publishing habit, not the one with the longest feature list. The best newsletter tool is the one you will actually use every week, with clean exports, honest analytics, and enough room to grow before you pay.
