Change the Default Admin Email for WordPress

Method 1: Using WP-CLI

The quickest way to change the admin email using WP-CLI:

wp option update admin_email new-email@example.com

Method 2: Direct Database Update

Add this code to your theme's functions.php file or in a site-specific plugin:

add_action('init', 'change_admin_email');

function change_admin_email() {
    update_option('admin_email', 'new-email@example.com');
}

Method 3: Using WordPress Hooks

This code changes the admin email for all WordPress notifications. Add to functions.php:

add_filter('wp_mail_from', 'custom_wp_mail_from');
add_filter('wp_mail_from_name', 'custom_wp_mail_from_name');

function custom_wp_mail_from($email) {
    return 'new-email@example.com';
}

function custom_wp_mail_from_name($name) {
    return 'Your Site Name';
}

Method 4: Using Constants

Add these lines to wp-config.php before the "/* That's all, stop editing! */" line:

define('WP_MAIL_FROM', 'new-email@example.com');
define('WP_MAIL_FROM_NAME', 'Your Site Name');
