@hube2 Hey, I think I’m missing something, because this isn’t sending the email:

function delegate_form_update($value, $post_id, $field) {

	$order = new WC_Order($post_id);

	// global email settings
	$to = get_option('admin_email');
	$headers = array('Content-Type: text/html; charset=UTF-8');

	// this will hold the number of rows - old value
	$old_rows = intval(get_post_meta($order, 'ticket_alloc', true));

	// count the rows submitted
	$new_rows = count($_POST['acf']['field_63ca95e88557a']); // field key of repeater

	if($old_rows != $new_rows) {
		// number of rows has changed		
		$subject = 'Number of rows has changed';
		$body = 'This is the mail body';
		wp_mail($to, $subject, $body, $headers);
	}

	return $value;

}
add_filter('acf/update_field/key=field_63ca95e88557a', 'delegate_form_update', 10, 1);
