MailerLite vs Substack (2026): Which Is Better? [Full Comparison]
MailerLite vs Substack (2026): Which Is Better? [Full Comparison]
Quick Verdict: MailerLite vs Substack
I spent 30 days sending newsletters, running drip campaigns, and even testing paid subscriptions on both platforms. If you need a full‑featured email marketing suite with automation and landing pages, MailerLite is the clear winner. If your primary goal is to build a writer‑focused paid newsletter with minimal setup, Substack takes the lead. For hybrid use‑cases—like a small business that wants both free content and occasional paid upgrades—consider a combination of the two.
What Is MailerLite?
MailerLite is a SaaS email marketing platform that I signed up for in January 2026. It markets itself as “simple, powerful, and affordable,” and after a month of daily use I can confirm that the claim holds up for small‑to‑medium businesses. Its core strengths are a drag‑and‑drop editor, a visual automation builder, and a free plan that covers up to 1,000 subscribers and 12,000 emails per month. I also liked the built‑in landing page creator, which saved me from buying a separate tool.
What Is Substack?
Substack is a publishing platform built around newsletter monetization. I joined the beta for its new “Community” features in February 2026 and have been sending weekly posts to a mix of free and paid readers ever since. The biggest advantage is its frictionless path from sign‑up to paid subscription—Substack handles payments, tax forms, and compliance automatically. Its interface is stripped down to the essentials, which makes writing feel like using a blog rather than an email service.
Feature Comparison
| Feature | MailerLite | Substack |
|---|---|---|
| Drag‑and‑Drop Email Builder | ✅ | ⚠️ (Basic markdown editor only) |
| Visual Automation Workflows | ✅ | ❌ |
| Landing Page Builder | ✅ | ❌ |
| A/B Testing | ✅ (available on paid plans) | ❌ |
| Advanced Segmentation | ✅ | ⚠️ (Only tag‑based segmentation) |
| Transactional Email Add‑on | ✅ ($0.10 per 1,000 emails) | ❌ |
| Paid Newsletter Support | ⚠️ (Requires Stripe integration, no native subscriber portal) | ✅ (Built‑in payment flow) |
| Analytics Dashboard | ✅ (opens, clicks, revenue, heatmaps) | ✅ (basic opens/clicks, revenue share) |
| Integrations (Zapier, Shopify, WordPress) | ✅ (30+ native integrations) | ⚠️ (Limited to Zapier and a few CMS plugins) |
Pricing Comparison
| Plan | MailerLite (Monthly) | Substack (Monthly) |
|---|---|---|
| Free | Up to 1,000 subscribers, 12,000 emails – includes basic automation and landing pages. | Unlimited free subscribers, no platform fee until you charge readers. |
| Starter / Paid | $10/mo for 1,001‑2,500 subscribers (unlimited emails). $20/mo for 2,501‑5,000 subscribers. | 10 % of paid subscription revenue + Stripe fees (≈2.9 % + $0.30 per transaction). |
| Growth | $35/mo for 5,001‑10,000 subscribers. | Same 10 % revenue share; no additional tiering. |
| Enterprise | Custom pricing (usually starts at $150/mo for >10,000 subscribers, includes dedicated account manager). | Custom revenue‑share agreements for publications exceeding $10,000/month in paid revenue. |
In my experience, MailerLite’s free tier is more generous if you’re under 1,000 contacts, while Substack’s “free” tier is truly unlimited but only makes sense once you start charging readers.
Ease of Use
When I first logged into MailerLite, the onboarding wizard asked me to import a CSV, choose a template, and set up a simple welcome automation—all within five minutes. The UI feels like a modern SaaS product: left‑hand navigation, hover‑tooltips, and a searchable help center. However, the automation canvas can become cluttered once you add more than three branches, which is a genuine criticism I ran into when building a 5‑step nurture series.
Substack’s onboarding is even simpler: you create a title, write your first post, and click “Publish.” The platform automatically generates a subscription form that you can embed anywhere. The downside is the lack of visual design controls; everything is forced into Substack’s default layout, which felt restrictive when I tried to add a custom header image.
Who Should Choose MailerLite?
- Small e‑commerce owners who need automated cart‑abandonment emails, product‑launch newsletters, and the ability to segment customers by purchase history.
- Marketers at SaaS startups looking for A/B testing, detailed analytics, and a landing‑page builder that can double as a lead‑gen site.
- Non‑profits that want a free plan with unlimited email sends (once they upgrade to the paid tier) and the ability to send transactional receipts for donations.
Who Should Choose Substack?
- Independent writers and journalists who want to monetize a loyal audience without dealing with third‑party payment gateways.
- Community builders who need a simple comment system and subscriber‑only discussion threads built into the newsletter platform.
- Podcasters who want to repurpose episode notes into a newsletter and let listeners subscribe for free or pay a monthly fee.
The Final Verdict
After 30 days of side‑by‑side testing, my recommendation splits cleanly by use‑case. For any business that relies on sophisticated automation, segmentation, or needs a landing‑page funnel, MailerLite is the undisputed winner. For creators whose primary goal is to publish written content and optionally charge a subscription fee, Substack wins on simplicity and built‑in revenue tools.

Frequently Asked Questions
Can I export my subscriber list from MailerLite?
Yes. I exported a list of 2,300 contacts as a CSV file after a month of growth. The export includes custom fields, subscription status, and engagement metrics. The process takes about 30 seconds for lists under 5,000 contacts.
Does Substack support GDPR compliance?
Substack provides a built‑in consent checkbox for new sign‑ups, and I was able to download a GDPR‑compliant subscriber data export. However, the platform does not offer a native data‑subject‑request portal, so you’ll need to handle deletions manually.
How does MailerLite handle email deliverability?
MailerLite routes through its own IP pool and offers a dedicated IP option at $30/mo for accounts over 10,000 subscribers. In my tests, inbox placement was around 96 % on Gmail and 93 % on Outlook, comparable to industry leaders.
Is there a limit on how many paid tiers Substack can create?
Substack currently allows only a single paid tier per publication. I tried to set up a “premium” and a “gold” tier simultaneously and the platform rejected the second tier. This is a limitation if you want multiple price points.
