Send data via JSON and decouple the View from Model
If you use our powerful editor to edit your Transactional Email Templates like we do for all our communications, then just send JSON as an email body in your code and we'll build the message for you.
E.g.: identify the template, run the template engine code (HandlebarsJS) and send the generated output (HTML or text).
This way, if you want to change something in your transactional email template, you don't have to wake up or bother the programmers of your site / app. Just edit the BODY of your email with our superb email editor.
