The easiest way to setup the plugin is to import the templates. Go to Email Builder – Settings, and click on Import to import the example templates and rules.
After that, you’ll have a working setup for all the default WooCommerce emails. In the bottom of the settings screen, you can set the default builder styles. You can also inspect and change the rules to match your workflow, and easily preview all the emails.
Once you’re happy with the templates, check the Enable sending custom emails toggle at the top of the Settings section to start using the new emails.
