email-template is a simple library used to render both a text and html template for a given data context.
usage is easy:
et.createBodies({text: path.join(__dirname, 'email/success.handlebars.text')}, data, callback);
The templating engine is determined by trying to match one of the exports from conosolidate.js with the filename, so you can either include the engine in the filename or in the path. Any of these will work:
sample.ejs.text
./handlebars/sample.html
