# Unhook and remove WooCommerce emails

This code allows you to unhook and remove the default WooCommerce emails.

Add this code to your child theme’s `functions.php` file or via a plugin that allows custom functions to be added, such as the [Code snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme’s `functions.php` file, as this will be wiped entirely when you update the theme.

```php
if ( ! function_exists( 'YOUR_PREFIX_unhook_woocommerce_emails' ) ) {
	/**
	 * Callback for woocommerce_email action hook
	 *
	 * @param WC_Email $email_class An Email class instance.
	 * @return void
	 */
	function YOUR_PREFIX_unhook_woocommerce_emails( $email_class ) {
		/**
		 * Hooks for sending emails during store events.
		 */
		remove_action( 'woocommerce_low_stock_notification', array( $email_class, 'low_stock' ) );
		remove_action( 'woocommerce_no_stock_notification', array( $email_class, 'no_stock' ) );
		remove_action( 'woocommerce_product_on_backorder_notification', array( $email_class, 'backorder' ) );

		// New order emails.
