A few days ago I've asked how I can rename custom email templates in WooCommerce. Now I have the problem that I have some email templates which I don't need and I want to hide these templates completely. How can I do this? I've searched on SO and Google but can't find a tutorial.

Update: The right solution is using woocommerce_email_classes filter hook locate in WC_Emails Class:

add_filter( 'woocommerce_email_classes', 'remove_specific_email_classes', 10, 1 );
function remove_specific_email_classes( $emails ) 
 unset($emails['WC_Email_New_Order']);
 unset($emails['WC_Email_Cancelled_Order']);
 unset($emails['WC_Email_Failed_Order']);
 unset($emails['WC_Email_Customer_On_Hold_Order']);
 unset($emails['WC_Email_Customer_Processing_Order']);
 unset($emails['WC_Email_Customer_Completed_Order']);
 unset($emails['WC_Email_Customer_Refunded_Order']);
 unset($emails['WC_Email_Customer_Invoice']);
 unset($emails['WC_Email_Customer_Note']);
 unset($emails['WC_Email_Customer_Reset_Password']);
 unset($emails['WC_Email_Customer_New_Account']);

 return $emails;

Code goes in function.php file of your active child theme (active theme). Tested and works.

The following official Woocommerce documented hooked function will remove notifications action hooks:

add_action( 'woocommerce_email', 'unhook_those_pesky_emails' );
function unhook_those_pesky_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
 remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_pending_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_failed_to_processing_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_failed_to_completed_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_failed_to_on-hold_notification', array( $email_class->emails['WC_Email_New_Order'], 'trigger' ) );

 // Processing order emails
 remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
 remove_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );

 // Completed order emails
 remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );

 // Note emails
 remove_action( 'woocommerce_new_customer_note_notification', array( $email_class->emails['WC_Email_Customer_Note'], 'trigger' ) );

Code goes in function.php file of your active child theme (active theme). Tested and works.

This is my solution. I'm not sure whats better?

add_filter( 'woocommerce_email_classes', 'remove_unused_emails', 15 );
function remove_unused_emails( $email_classes ) 

 //Unset unused email templates
 unset( $email_classes['WC_Email_Customer_Reset_Password'] );
 unset( $email_classes['WC_Email_Customer_New_Account'] );
 unset( $email_classes['WC_Email_Customer_On_Hold_Order'] );
 unset( $email_classes['WC_GZD_Email_Customer_New_Account_Activation'] );
 unset( $email_classes['WC_GZD_Email_Customer_Revocation'] );
 unset( $email_classes['WC_GZD_Email_Customer_Ekomi'] );
 unset( $email_classes['WC_GZD_Email_Customer_Trusted_Shops'] );

 return $email_classes;
