Instead of customizing default email templates you are recommended to create your own templates and set Magento 2 to use them instead of the default ones. In this case, you can add unique templates as physical files in your theme or create them using the Admin Panel. We are going to describe how to create the templates via the Admin Panel.

Template Name: enter the name you want to identify the template in the Admin Panel;
Template Information: fill in the subject of the email template, which is to be displayed in the subject line once it’s sent. The field can include system variable if you choose them:
Template Content: type in the content of the future template;
Template Style: add CSS styles for the template in the field. The style elements will be included in the <head> tag of the file put between tag <style>...</style>.
