WooCommerce send customers and store admins emails when new orders are placed, these emails contains all sorts of info relating to the order, however it is missing a couple of things that can be useful to customers or store admins.

One of the fields that is not present in the WooCommerce order emails are the payment type, some WooCommerce store admins would perhaps want to know this data in emails for decisions on whether to ship items immediately or to hold off for a while for money to clear.

To add the payment type to all WooCommerce emails or just admin email add the following code to your theme’s functions.php file, this is upgrade safe and the changes will stay in place after WooCommerce updates.
