Change sender name and email address for specific WooCommerce email notifications

问题

How to change email sender address and name in WooCommerce for specific email notifications?

For example:
Change the sender name and email address just for customer processing order email notifications.

But not for all email notifications, just for specific ones.

回答1:

The sender name and email address are set here (at the end of Woocommerce "Emails" setting tab:

This fields are passed through dedicated filters hook that allow you to change conditionally the values.

Here is an example conditionally restricted to "customer processing email notification":

// Change sender name
add_filter( 'woocommerce_email_from_name', function( $from_name, $wc_email ){
    if( $wc_email->id == 'customer_processing_order' ) 
        $from_name = 'Jack the Ripper';

    return $from_name;
}, 10, 2 );

// Change sender adress
add_filter( 'woocommerce_email_from_address', function( $from_email, $wc_email ){
    if( $wc_email->id == 'customer_processing_order' )
        $from_email = 'jack.the.ripper@freek.com';

    return $from_email;
}, 10, 2 );

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.

Some other WC_Email Ids that you can use in your condition: - 'customer_completed_order'
- 'customer_on_hold_order'
- 'customer_refunded_order'
- 'customer_new_account'
- 'new_order' ( admin notification )
- 'cancelled_order' ( admin notification )
- 'failed_order' ( admin notification )
