Step 1: Create a Custom Email Template

First things first, you’ll need to create a custom email template to use as the foundation for your email designs. To do this, you’ll need to create a new folder called woocommerce inside your theme folder, and then create a subfolder called emails.

Next, copy the email template you want to customize from the woocommerce/templates/emails folder of the WooCommerce plugin to the woocommerce/emails folder of your theme. For example, if you want to customize the new order email template, copy the email-order-details.php file from the plugin to your theme.

Now comes the fun part: let your creativity run wild! You can customize the email template using standard HTML and CSS. Add some branding elements, change the layout, or modify the content of the email. Just make sure to keep it professional and avoid using Comic Sans. No one likes Comic Sans.

Step 2: Override the Default Email Template

Once you’ve created a custom email template, it’s time to override the default template using the woocommerce_email_{$email_id}_template hook. This hook allows you to specify a custom template for a specific email type.

To override the default email template, add the following code to your theme’s functions.php file:

Just remember to replace {$email_id} with the ID of the email you want to customize (e.g. new_order for the new order email).

Step 3: Test the Customized Email

Now it’s time to see if all your hard work has paid off! To test the customized email, simply place an order on your website. If everything is set up correctly, you should receive the customized email instead of the default email.

If you encounter any issues, you can troubleshoot them by enabling the WordPress debug log and checking the log for any error messages. You can also try using the wp_mail_failed action hook to debug email issues.

In conclusion, customizing the appearance of WooCommerce emails using custom code is a great way to make your emails more visually appealing and consistent with your brand. Just make sure to keep it professional, and avoid using Comic Sans at all costs. Your customers will thank you.
