Email Lab
This a project for developing and testing email templates. It uses Grunt, a command-line build tool, to streamline and simplify the creation of email templates. Email template can be built with re-usable components (like header and footer) and can be styled using traditional CSS or Sass that will be compiled into normal CSS. The build tool will convert these traditional styling rules into embedded and inlined styles required for HTML in most email clients.
See the tools section below for more information.
Setup and Installation
You will need the following tools installed in order to complete the setup (install notes are for Mac).
- Node.js - If you are on a Mac install Node with Homebrew (
brew install node
). - Grunt.js - For workflow automation (install with
npm install -g grunt-cli
) - Bundler - For managing Ruby Gem dependencies (install with
gem install bundler
)
Once these are installed successfully complete the following steps to setup the project (run commands from the project root directory).
- Run the command
bundle install
to install required Ruby Gems - Run the command
npm install
to install required node packages - Copy
settings.sample.json
tosettings.json
and configure the following:- From email address
- Default To email address
- SMTP Provider settings (see a full list of supported providers)
That's it! Sing and dance. The email template code is ready for development and testing.
Setup and Installation with Docker
You will need the following tools installed in order to complete the setup.
Once these are installed successfully complete the following steps to setup the project (run commands from the project root directory).
- Copy
settings.sample.json
tosettings.json
and configure the following:- From email address
- Default To email address
- SMTP Provider settings (see a full list of supported providers)
- Run the command
docker-compose up
to build and run the docker image.
Once it finishes, you can access the email templates at http://localhost:9000/ in your browser.
That's it! Sing and dance. The email template code is ready for development and testing.
When you are done with development, you will want to remove the project from Docker.
Run command docker-compse down
to remove the docker container.
Grunt
Grunt is a tool for automating workflow tasks. It is configured to easily preview, test and build your templates.
- Preview/Develop - Run
grunt server
to launch the templates in a browser. This will also watch for file changes and update each time you save, including compiling SASS into CSS. - Build - Run
grunt
orgrunt build
to compile all your code for production into the/dist
directory. - Test - Run
grunt send
to email your templates to a testing service like Litmus. To send just one email template use the template parameter like thisgrunt send --template=order-confirmation
where the template value is the basename of the template file. Use the--to
parameter to provided a specific address to mail to (ie.grunt send [email protected]
).
Tools
This Grunt workflow allows you to create emails like you would standard web pages, separating your HTML from your CSS.
Sass
Node Sass is used to compile Sass files into standard CSS. Each email template will have it's own
Sass file. Sass files are associated with specific templates simply by naming them with the same
basename as the HTML template file for the email (ie. contact-confirmation.html
--> contact-confirmation.scss
).
Premailer
The Premailer plugin is used during builds to convert the styles from linked stylesheets into embedded and inlined styles in the template since email clients do not support linked stylesheets.
Nodemailer
The Nodemailer plugin is used to send your email
templates to test email addresses for testing. You'll need to configure a nodemailer.json file
to use the SMTP service from your Gmail address or other service. See /settings.sample.json
for more details and a list of supported SMTP services.
Handlebars/Assemble
Handlerbars and Assemble are used
to dynamically build your templates with re-usable layouts. To create a new email
template simply create a new file in src/templates/emails
with the .hbs extension.
HTML Email Design
This project provides some standard boilerplate HTML markup and styling for emails. We recommend checking out these other resources for additional layout templates and styling best practices:
- HTML Email Boilerplate - Well-documented boilerplate template
- Mailchimp Email Blueprints - Lots of template for various layouts, including responsive template
- Mailchimp Email Design Reference - Great reference guide for designing HTML emails
- Email Client Market Share - List of the most popular email clients
Todo
- Create Yeoman generator that configures options, sets up Nodemailer and generates new email templates
- Handle images locally during dev, but replace with hosted images for testing
