You can see an example setups below

Getting Started

Install this gulp plugin next to your project's gulpfile with: npm install gulp-email-builder

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

var emailBuilder = require('gulp-email-builder');


Place this in your gulp file.

  gulp.task('emailBuilder', function() {
    return gulp.src(['./example/html/*.html'])

Other available methods

Besides the main emailBuilder(options).build() function, the email-builder-core methods are exposed so users can use them on an individual basis.

  • emailBuilder(options).inlineCss()
  • emailBuilder(options).sendEmailTest()
  • emailBuilder(options).sendLitmusTest()




View Email Builder options for all available options.

Complete Example

var EmailBuilder = require('gulp-email-builder');

var options = { encodeSpecialChars: true }
var builder = EmailBuilder(options);

gulp.task('emailBuilder', function() {
  return gulp.src(['./example/html/*.html'])


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 they're having any issues. If that's not the case, submit an issue and we'll look into further.
