How can I send data from product field in E-mail?

Here is product fields data that I use.

Hi @pattice

You mean the order information when an order is created?

Yes, information that customers must fill in on that product page.

Our plugin stores its data as standard order item meta data. So by using default WooCommerce functions, you can fetch all order item meta data and it will include the information your customer filled out on the product page.
