Custom Order Status by Nuggethon

Step 1: Created Statuses

Go to WooCommerce > Custom Order Statuses > Add New Custom Order Status

You can go to WooCommerce > Settings > Emails to edit the email subject and heading, and remember to enable the email notification because it is disabled by default.

Once the status has been changed, it will automatically send an email to the customer.

Step 2: Design custom order status email

After you successfully set up a new order status, you will see a new email template nested under the template selector.

Please choose a template and customize it.

And don't forget to enable and Save it!
