Choose Substack if you want the fastest public newsletter with built-in discovery; choose MailerLite if you want more control, better email tools, and a cleaner path to selling later. Substack is free to start and makes money when you sell paid subscriptions, taking 10% of subscription revenue [source: Substack]. MailerLite feels more like a full email marketing platform, with signup forms, automations, landing pages, and segmentation. Both can build an audience, but they serve very different kinds of creators.
TLDR: Substack is best for writers, commentators, educators, and niche experts who want to publish quickly and grow through sharing, recommendations, and searchable posts. MailerLite is better for creators who want to build a list they control, run campaigns, test subject lines, and connect email to products or services. For example, a solo writer with 2,000 free readers and 100 paid members at $8 per month may prefer Substack for simplicity, even after the 10% platform fee. A coach with 800 subscribers, three lead magnets, and a $299 course will usually get more value from MailerLite’s forms, automations, and audience tagging.
What “free newsletter website” really means
A free newsletter website is more than a place to send emails. It is your public archive, signup page, publishing tool, and often your first brand home. Substack and MailerLite both give you a way to publish without hiring a developer or paying for web hosting. That is the easy part.
The hard part is choosing the tool that matches how you want to grow. Substack treats your newsletter like a publication. MailerLite treats it like an email marketing system. That difference sounds small. It is not.
Substack: best for publishing and audience momentum
Substack is built around writing. You create a publication, write posts, send them as emails, and publish them on a public page. Readers can browse your archive, comment, share posts, and recommend your newsletter to others. The setup is refreshingly quick.
If your main product is your voice, Substack is hard to beat. Essays, analysis, cultural commentary, industry notes, personal updates, fiction, and paid columns all fit well. You can start with free posts, then add paid subscriptions when the audience trusts you.
What Substack does well:
- Fast publishing: You can write and send a post without building a funnel first.
- Built-in reading habits: Subscribers know what Substack is and often already have accounts.
- Paid subscriptions: Turning on monetization is simple.
- Discovery features: Recommendations and the Substack app can help new readers find you.
- Public archive: Posts can work like blog articles and be shared easily.
The annoying part is the limited control. Substack is simple because it keeps choices tight. That is great until you want advanced design, detailed automations, complex tagging, or a custom subscriber journey. Honestly, it feels like you hit the ceiling right when your audience starts getting serious.
MailerLite: best for control and email marketing
MailerLite is a better fit if you care about list building as a business asset. It gives you forms, landing pages, automation workflows, groups, segments, surveys, and email templates. It is not just for newsletters. It is for campaigns.
That matters if you sell courses, consulting, digital products, memberships, events, or services. You can create a free guide, collect emails from a landing page, tag subscribers by interest, and send different sequences based on what they clicked. Substack cannot match that depth.
What MailerLite does well:
- Signup forms: Embed popups, forms, and landing pages across your site.
- Audience segmentation: Group readers by behavior, source, or interest.
- Automations: Send welcome sequences, sales emails, and nurture campaigns.
- Design control: Build branded emails without starting from scratch.
- Business use: Connect newsletters to products, bookings, courses, and promotions.
Expect to waste time on setup if you are brand new to email marketing. MailerLite gives you more knobs to turn, so there is more to break. A simple welcome flow might take 30 to 45 minutes the first time, especially if you are fiddling with forms, groups, and email timing.
Audience growth: Substack has the friendlier start
Substack wins the early growth battle for many writers because it has a social layer. Readers can discover you through recommendations, notes, comments, shares, and other writers. That makes it feel less lonely than sending emails into the void.
For a new creator with no website, no lead magnet, and no ad budget, Substack removes friction. You can publish an opinion piece in the morning and share it by lunch. The page looks decent. The subscribe button is obvious. The archive is ready.
MailerLite can grow an audience too, but it usually needs traffic from somewhere else. That might be a blog, YouTube channel, podcast, Instagram account, paid ads, webinars, or search traffic. MailerLite captures and manages demand. Substack can help create some of it.
Design and branding: MailerLite has the edge
Substack pages look clean, but they also look like Substack. You can adjust some basics, use a custom domain, and add publication branding. Still, the structure is familiar. For some readers, that is comforting. For brands, it can feel limiting.
MailerLite gives you broader creative control. You can build landing pages for different offers, create branded email templates, and match your site more closely. If your newsletter is part of a larger business, this matters. A fitness coach, for instance, may want one landing page for meal planning, one for strength training, and one for a paid challenge.
Monetization: simple vs strategic
Substack makes paid newsletters easy. You can charge monthly or yearly, offer free and paid posts, and manage subscribers in one place. This is ideal if your content itself is the product.
MailerLite is better when monetization happens around the newsletter. You might use email to sell a course, book calls, promote affiliate offers, launch templates, or announce events. The newsletter supports the business, rather than being the whole business.
Here is a quick way to think about it:
- Paid essays or premium commentary? Pick Substack.
- Digital products or service sales? Pick MailerLite.
- Community around a writer? Pick Substack.
- Multiple lead magnets and sales paths? Pick MailerLite.
Analytics and subscriber data
Substack gives you useful basics. You can see subscribers, opens, paid conversions, traffic sources, and post performance. For writers, that may be enough. You learn which topics pull readers in and which posts drive subscriptions.
MailerLite goes deeper for campaign analysis. You can track groups, segments, automation performance, clicks, forms, landing pages, and subscriber behavior. If you want to compare two lead magnets or measure how many readers clicked a product link, MailerLite is stronger.
This is where the difference becomes practical. If one article gets a 48% open rate on Substack, you know readers liked the topic. If one MailerLite segment clicks a sales page at 12% while another clicks at 3%, you can change your offer, timing, or message.
Which one should you choose?
Use Substack if you want to write, publish, and build a loyal readership with minimal setup. It is excellent for solo creators who value speed and reader connection over marketing complexity. It is also a smart choice if you want to test an idea before building a full website or sales system.
Use MailerLite if your newsletter is part of a broader business plan. It is the better tool for structured growth, polished campaigns, audience tagging, and automated sales paths. It takes more setup, but the extra control pays off once your list has different types of subscribers.
The simplest rule is this: Substack is a publishing home; MailerLite is an audience management tool. If you want readers to gather around your writing, start with Substack. If you want to guide subscribers toward products, services, or targeted offers, start with MailerLite.
You can also combine them later. Some creators publish public essays on Substack, then move serious business funnels into MailerLite. That setup is not for everyone, but it works when your audience grows beyond simple weekly updates. Start with the tool that matches your next 90 days, not your dream system two years from now.
