Mailwind

Use Tailwind CSS to design HTML emails.

Tailwind makes it very easy to design websites, why not use it to design HTML emails? I've been using this for volt.fm and pikaso.me and it has made my life a lot easier.

Install

npm install -g mailwind

Usage

Design your HTML email using the Tailwind utility classes like you normally would for the web.

Then run the following command to generate the corresponding CSS file:

mailwind --input-html email.html --output-css style.css

Or run this command to generate an inlined HTML file:

mailwind --input-html email.html --output-html email-inlined.html

Options

--input-css

The path to your base CSS file. Use this if you need to write custom CSS. Defaults to style.css.

--input-html

The path to your HTML email file.

--output-css

The path to the CSS file that will be generated.

--output-html

The path to the inlined HTML file that will be generated.

--tailwind-config

The path to your custom Tailwind configuration file. Defaults to tailwind.config.js.

Note

In the provided default config file, all the units are changed to pixel which is probably what you want for HTML emails.

Example

Given an email.html file with this content:

<html>
  <body>
    <p class="font-bold text-lg">Welcome</p>
  </body>
</html>

running this command:

mailwind \
  --input-html email.html \
  --output-css style.css \
  --output-html email-inlined.html

will generate the following CSS and inlined HTML files:

.text-lg {
  font-size: 18px
}

.font-bold {
  font-weight: 700
}

<html>
  <body>
    <p class="font-bold text-lg" style="font-size: 18px; font-weight: 700;">Welcome</p>
  </body>
</html>
