Explanation

Want to add a personal touch to your WooCommerce order confirmation emails? This snippet lets you include a custom note in the emails sent to your customers when their order is being processed.

Where it goes: This code hooks into the part of WooCommerce that handles email order details.
What it does: It checks if the email being sent is the "customer processing order" email. If it is, it adds a custom message to the email.
Customizing the message: You can change the text in the $custom_note variable to whatever message you want to send to your customers.
Plain text vs. HTML: The code handles both plain text and HTML emails, ensuring your message looks good no matter what format your customer receives.

Simply adjust the message to fit your brand's voice, and your customers will receive a warm, personalized note with their order confirmation. Easy peasy!

        // Define your custom note
        $custom_note = __('Thank you for your order! We appreciate your business and hope you enjoy your purchase.', 'text-domain');

        // Output the custom note
        if ($plain_text) {
            echo "\n" . $custom_note . "\n"; // For plain text emails
        } else {

        }
    }
