Testing and Building the Template
Maizzle CLI provides us with the option to watch the changes in the browser. You can edit them and see your changes in a browser, and better than best
browsersync automatically reloads the browser even time you save a change in your editor. Open
http://localhost:3000 to see your rendered template.
Now if you check the size of your html file, it weighs a whopping 400+ KB, not ideal for an email. BUT, after you build your production build it will be much less.
Building the template
maizzle build production will build the templates and save them in a folder
build_production. while building the templates maizzle removes all the unused CSS styles and make the templates as small as you can think of.
