Currently Complete customization requires you going into the code and editing the required php template files, which is not a really an easy option for a non-programmer, and you can be slow even if you are a programmer. We wanted to give you an easiest environment that is may more simple to use, and gives you a live preview of your customizations, so that you can comfortably send a test email when you are done. That is what this premium plugin does for you.
The plugin also adds premium functionality to your WooCommerce Orders page so you are able to open a preview of any of the email templates such as Processing Order, Invoice, New Order, etc. It also send or resend that email to your customer or yourself
