Two custom fields in New order notification email?

Per the forums rules, we are not able to support for premium extensions here. This forum is only for WooCommerce core. You will need to contact support from where you purchased the plugin.

Ok. So we write direct in automatic web with question on custom field plugin.

But what when we want for example write static text
“Děkujeme za Va?i rezervaci vozu a p?ejeme mnoho ujetych km.”

how we can add this static text on bottom between client address and footer? We tryed now many manuals whats are on internet but not help. We reach only, that we can add this text before client address, but we need have it between client address and footer.

There are two ways to edit email templates.

1) Override the template in your child theme following this guide: https://docs.woothemes.com/document/template-structure/. Here are the email templates: https://github.com/woocommerce/woocommerce/tree/master/templates/emails

2) Use the available hooks and filters in a code snippet in your child theme or in a customer plugin.

Guys we bought oficial plugin Woocommerce Custom Fields
