Email template structure

The structure of an email template is not set in stone and can be easily customized. In some of the third-party extensions, it is possible to find email templates that do not know the key parts of an email, which are:

  <!--@subject {{trans "Welcome to %store_name" store_name=$store.frontend_name}} @-->

• Variable definition: The email subject is followed by a list of variables that are used in the template file along with their sample values. The following is an example from a customer registration email:

  <!--@vars {
  "var store.frontend_name":"Store Name",
  "var this.getUrl($store,'customer/account/',[_nosid:1])":"Customer Account URL",
  "var customer.email":"Customer Email",
  "var customer.name":"Customer Name",
  "var this.getUrl($store,'customer/account/createPassword/...
