Also, the Email customizer plugin is compatible with the Themehigh Checkout Field Editor For WooCommerce. The fields of the Checkout Field Editor plugin will be passed to the default WooCommerce hooks.
The email customizer lets the checkout fields display anywhere in the email template using a shortcode:
[WCFE name='field_name' label='field_label']
Using the shortcode given below, you can display the value without a label. Also, try not to use double quotes inside the shortcode.
[WCFE name='field_name']
