How to customize order confirmation e-mail I am experimenting with Commerce 2 and it is amazing, however one thing that I am unable to resolve customizing store e-mails? The default confirmation is not adequate and should be easy to customize using tokens or whatever like drupal core email messages. Can anybody provide a high level overview how to customize the order summary e-mail? Any tips will be greatly appreciated not only by myself, but certainly many other site builders who are stumped over this.
Order receipt emails are powered by Twig templates, just like regular pages. This helps us avoid the inflexibility of tokens and their lack of conditional support ("Only show the Shipping information heading if the token has data"), which were big problems for D7 sites.

You can override the commerce-order-receipt.twig.html template in your theme to customize it.
