Supercharge your email development workflow

Maizzle empowers you with modern web development tools, enabling fast email prototyping while keeping your entire team on-brand.

Who said CSS frameworks should only be used for websites? Maizzle uses the Tailwind CSS framework, so you can rapidly prototype beautiful, on-brand HTML emails. Forget about writing inline styles.

Utility-first CSS

Tailwind CSS provides low-level utility classes that help you style emails much faster than manually writing inline CSS.

Powerful modifiers

Use powerful variant classes like hover:bg-blue-500 or sm:w-full to easily add hover effects or style responsive emails.

Make it your own

Easily create or bring in your own email design system, keeping everyone in your team on-brand.

<extends src="src/layouts/main.html">
  <block name="template">
    <table class="w-150 sm:w-full">
        <td class="text-base text-gray-700">
          <p>Bring your own HTML</p>


Code with markup you already know.

Bring Your Own HTML

No need to learn custom syntax or adapt your templates to it. Use your existing HTML if you prefer, it'll just work.

Supercharged by PostHTML

PostHTML gives your HTML superpowers, enabling components and complex logic through simple, text editor-friendly markup.

module.exports = {
  build: {
    templates: {
      source: 'src/templates',
      destination: {
        path: 'build_production',
        extension: 'html',
      assets: {
        source: 'src/images',
        destination: 'images',

Build Environments

Custom build scenarios, easily configured in JavaScript.

Using fake data locally, but need to fetch content from an API in production? Prettified email markup for your colleagues? All possible.

CLI Commands

Each build environment config enables its own CLI build command, so you can build the same templates in as many ways as you need.

Opt-in Transformers

Choose which post-processing transformations Maizzle applies to your HTML emails, on a build environment-basis.

Override from Template

Define or override data for each template just before it's compiled, through YAML Front Matter variables.
