React Email vs MJML vs Maizzle: Best Email Template Framework (2026)
HTML email is stuck in 1999. Tables, inline styles, Outlook quirks — it's the worst development experience in web technology. These frameworks try to make it bearable.
React Email uses React components. MJML uses a custom markup language. Maizzle uses Tailwind CSS. Each takes a fundamentally different approach.
Quick Comparison
| Feature | React Email | MJML | Maizzle |
|---|---|---|---|
| Approach | React components | Custom markup | Tailwind CSS |
| Syntax | JSX | XML-like tags | HTML + Tailwind |
| Rendering | Server-side React → HTML | MJML → HTML | Build step → inlined HTML |
| Preview | Built-in dev server | MJML Live (online) | Built-in dev server |
| Responsive | Components handle it | Built-in responsive | Tailwind responsive |
| Outlook support | Good | Excellent | Excellent |
| TypeScript | First-class | Limited | Via config |
| Component reuse | React components | Includes/partials | Layouts + partials |
| Community | Growing fast | Large, mature | Active |
| Learning curve | Low (if you know React) | Low | Low (if you know Tailwind) |
React Email: Components for Email
React Email lets you build emails using React components, then renders them to email-compatible HTML.
How It Works
import { Html, Head, Body, Container, Text, Button } from '@react-email/components';
export default function WelcomeEmail({ name }: { name: string }) {
return (
<Html>
<Head />
<Body style={{ backgroundColor: '#f6f9fc', fontFamily: 'sans-serif' }}>
<Container style={{ maxWidth: '600px', margin: '0 auto', padding: '20px' }}>
<Text style={{ fontSize: '24px', fontWeight: 'bold' }}>
Welcome, {name}!
</Text>
<Text>Thanks for signing up. Here's what to do next:</Text>
<Button
href="https://example.com/dashboard"
style={{ backgroundColor: '#000', color: '#fff', padding: '12px 20px', borderRadius: '5px' }}
>
Go to Dashboard
</Button>
</Container>
</Body>
</Html>
);
}
Strengths
- React mental model. If you build web apps in React, emails feel natural. Same components, same patterns.
- Type-safe. Full TypeScript support. Props are typed. Catch errors at build time.
- Built-in preview.
email devstarts a local server showing all your email templates with live reload. - Dynamic content. React props make personalization natural. Pass data, render conditionally.
- Growing ecosystem. Pre-built components from the community. Integrations with Resend, SendGrid, and others.
- Server-side rendering. Use
render()to convert React components to HTML strings — works with any email provider.
Weaknesses
- Inline styles only. No CSS classes — everything is inline
styleobjects. Gets verbose. - Outlook can be tricky. While components handle most quirks, edge cases in Outlook still require manual fixes.
- React dependency. If your backend isn't JavaScript/TypeScript, integration is harder.
- Newer project. Less battle-tested than MJML across email clients.
- No Tailwind. You write style objects, not utility classes. Less ergonomic for Tailwind users.
Best For
React/Next.js developers who want emails to feel like the rest of their codebase. Teams already using Resend for email delivery.
MJML: The Email Markup Standard
MJML (Mailjet Markup Language) has been the standard for email templating since 2015. It abstracts away email HTML complexity with semantic, email-specific tags.
How It Works
<mjml>
<mj-body background-color="#f6f9fc">
<mj-section>
<mj-column>
<mj-text font-size="24px" font-weight="bold">
Welcome, {{name}}!
</mj-text>
<mj-text>
Thanks for signing up. Here's what to do next:
</mj-text>
<mj-button href="https://example.com/dashboard" background-color="#000">
Go to Dashboard
</mj-button>
</mj-column>
</mj-section>
</mj-body>
</mjml>
Strengths
- Best email client compatibility. 8+ years of production use. MJML's output works in every email client including ancient Outlook versions.
- Semantic tags.
<mj-section>,<mj-column>,<mj-button>— describe what you want, not how to implement it with tables. - Language-agnostic. MJML compiles to HTML. Use from any backend: Node.js, Python, PHP, Ruby, Go.
- MJML Live. Online editor (mjml.io/try-it-live) for quick prototyping.
- Responsive by default. Columns stack on mobile automatically. No media query management.
- Large ecosystem. Plugins, integrations, and community templates. Used by major companies.
Weaknesses
- Custom markup language. Learning
<mj-section>,<mj-column>, etc. is another thing to remember. - Limited interactivity. Template logic requires a templating engine (Handlebars, Nunjucks) on top of MJML.
- No component model. Includes and partials exist but aren't as composable as React components.
- Inline styles in output. The generated HTML has massive inline styles (by design, for compatibility).
- Less TypeScript-friendly. MJML itself doesn't benefit from TypeScript.
Best For
Teams that need maximum email client compatibility, use non-JavaScript backends, or want the most proven email framework.
Maizzle: Tailwind CSS for Email
Maizzle lets you write emails using Tailwind CSS classes, then transforms them into email-compatible HTML with inlined styles.
How It Works
<x-main>
<table class="w-full">
<tr>
<td class="bg-gray-100 p-6">
<table class="w-150 mx-auto bg-white rounded-lg shadow-sm">
<tr>
<td class="p-8">
<h1 class="text-2xl font-bold text-gray-900 m-0">
Welcome, {{ name }}!
</h1>
<p class="text-gray-600 mt-4">
Thanks for signing up. Here's what to do next:
</p>
<a href="https://example.com/dashboard"
class="inline-block bg-black text-white px-6 py-3 rounded-md no-underline mt-4">
Go to Dashboard
</a>
</td>
</tr>
</table>
</td>
</tr>
</table>
</x-main>
Strengths
- Tailwind CSS. If you use Tailwind in your web app, emails use the same utility classes. Zero context switching.
- Full Tailwind config. Use your existing
tailwind.config.js. Same colors, spacing, fonts. - Build step handles everything. CSS inlining, purging unused styles, minification, URL processing.
- Layouts and components. Template inheritance and components for reusable email parts.
- Excellent Outlook support. MSO conditionals and Outlook-specific utilities built in.
- Browsersync preview. Live-reload development with previews.
- Framework-agnostic output. Produces plain HTML — works with any email provider or backend.
Weaknesses
- Still writing tables. Maizzle makes styling easier, but you're still structuring with HTML tables for compatibility.
- Less abstraction than MJML. You need to know email HTML patterns (tables, MSO conditionals). MJML hides this.
- Build configuration. Maizzle has a build system to configure (environment-specific settings, transformers).
- No dynamic rendering. Template variables use a simple templating engine, not React's expressiveness.
- Smaller community than MJML.
Best For
Tailwind CSS users who want consistent styling between web app and emails. Teams that want maximum control over the HTML structure.
Compatibility Comparison
| Email Client | React Email | MJML | Maizzle |
|---|---|---|---|
| Gmail (Web) | ✅ | ✅ | ✅ |
| Gmail (Mobile) | ✅ | ✅ | ✅ |
| Apple Mail | ✅ | ✅ | ✅ |
| Outlook 365 | ✅ | ✅ | ✅ |
| Outlook 2019 | ⚠️ (mostly) | ✅ | ✅ |
| Outlook 2016 | ⚠️ (mostly) | ✅ | ✅ |
| Yahoo Mail | ✅ | ✅ | ✅ |
| Samsung Mail | ✅ | ✅ | ✅ |
MJML and Maizzle have an edge in legacy Outlook compatibility due to more mature handling of MSO conditional comments.
Integration with Email Providers
All three produce HTML strings that work with any email provider:
- Resend: React Email has the tightest integration (same team). MJML and Maizzle work via HTML string.
- SendGrid: All three work. MJML has official SendGrid templates support.
- Amazon SES: All three work via HTML string.
- Postmark: All three work via HTML string.
FAQ
Which produces the smallest HTML output?
Maizzle (with CSS purging). React Email and MJML produce larger output due to inline styles, but email HTML size rarely impacts deliverability.
Can I use React Email with a Python/Go backend?
Yes, but you'd need a Node.js service to render the templates. Alternatively, pre-render templates to HTML and use them as strings. MJML or Maizzle may be simpler for non-JS backends.
Do I need a framework at all?
For simple transactional emails (password reset, welcome), a hand-coded HTML template might be fine. For marketing emails, newsletters, or anything with complex layout — use a framework.
Which has the best developer experience?
React Email for React developers. Maizzle for Tailwind developers. MJML for everyone else. There's no universal "best."
The Verdict
- React Email if you're a React developer, especially using Resend. Emails feel like building UI components.
- MJML if you need maximum compatibility, use a non-JS backend, or want the most proven solution.
- Maizzle if you're a Tailwind CSS user who wants consistent styling and maximum HTML control.
For most JavaScript/TypeScript teams in 2026, React Email offers the best developer experience. If legacy Outlook compatibility is critical, MJML is the safest choice.
