npm version Build Status Dependency Status Built with Grunt Gitter

Uses Email Builder to inline css into HTML tags, send tests to Litmus, and send test emails to yourself.

As of v3.0.0, you will no longer be able to use the data-ignore attribute. Instead, use data attributes data-embed and data-embed-ignore to prevent email builder from inlining css styles.


<!DOCTYPE html>
  <!-- styles will be inlined -->
  <link rel="stylesheet" type="text/css" href="../css/styles.css">
  <!-- styles will be embedded -->
  <link rel="stylesheet" type="text/css" href="../css/otherStyles.css" data-embed>
  <!-- link tag will be preserved and styles will not be inlined or embedded -->
  <link href='' rel='stylesheet' type='text/css' data-embed-ignore>
  <!-- styles will be inlined -->
    p { color: red; }
  <!-- styles will be embedded -->
  <style data-embed>
    h1 { color: black; }

You can see an example setups below

Getting Started

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-email-builder

Then add this line to your project's grunt.js gruntfile:



Place this in your grunt file.

emailBuilder: {
  test :{
    files : {
      'dest/ouput.html' : 'src/input.html'

To build your files dynamically

files : [{
  expand: true,
  src: ['**/*.html'],
  dest: 'dest/',


View Email Builder options for all available options.

Example Usage

  inline: {
    files: { 'dest/output.html' : 'src/input.html' },
    options: {
      encodeSpecialChars: true
  litmus: {
    files: { 'dest/output.html' : 'src/input.html' },
    options: {
      encodeSpecialChars: true,
      litmus: {
        username: 'username',
        password: 'password',
        url: '',
        applications: ['gmailnew', 'ffgmail', 'chromegmail']
grunt.registerTask('inline', 'emailBuilder:inline');
grunt.registerTask('litmus', 'emailBuilder:litmus');


If you're having issues with Litmus taking forever to load a test or the title of the test is showing up as "No Subject", it is most likely an issue with the Litmus API. You can check the Litmus status page to find out if their having any issues. If that's not the case, submit an issue and we'll look into further.


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
