问题
With the help of this page I've added an additional email to the WooCommerce emails. I wanted it te be a manual email that I can send to the customer, but it's not showing up in the order in the dropdown list of emails to send. I'm guessing I'm missing something, but I don't know what. This is de code of the plugin I use:
<?php

'html' => __( 'HTML', 'woocommerce' ),
'multipart' => __( 'Multipart', 'woocommerce' ),
)
)
);
}
} // end \WC_Expedited_Order_Email class
I've commented out the triggers and added the code for it to be a manual customer mail.
function is_customer_email() {
return true;
}
function is_manual() {
return true;
}
In the WooCommerce settings I see the mail and it looks like a manual mail that can be send to the customer. The mailtemplates look good, but I don't see the name of the mail in the dropdown in the order to really send it. What am I missing here?

You missed to add "Send Expedited email" action to "ORDER actions" Metabox dropdown as follow:
// Adding 'Send Expedited email' to action Metabox dropdown in admin order pages
add_filter( 'woocommerce_order_actions', 'filter_wc_add_send_expedited_email_action', 20, 1 );
function filter_wc_add_send_expedited_email_action( $actions ) {
$actions['send_expedited_email'] = __( 'Send Expedited email', 'woocommerce' );
return $actions;
}
// Trigger the email notification on 'Send Expedited email' action (composite hook)
add_action( 'woocommerce_order_action_send_expedited_email', 'trigger_action_send_expedited_email', 20, 1 );
function trigger_action_send_expedited_email( $order ) {
// Get all WC_emails objects instances
$wc_emails = WC()->mailer()->get_emails();
// HERE We define our custom email class name
$class_name = 'WC_Expedited_Order_Email';
// Send custom email
if( class_exists($class_name) ) {
$wc_emails[$class_name]->trigger( $order->get_id() );
}
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
I didn't really tried with your custom email code, as the custom related templates are missing from your answer code… You should add your complete code to a public Gist on Github and then add the link to your answer (useful for the community).

I added:
function sv_wc_process_order_meta_box_action( $order ) {
// add the order note
$message = sprintf( __( 'Herinnering verstuurd door: %s.', 'label20-textdomain' ), wp_get_current_user()->display_name );
$order->add_order_note( $message );
}
add_action( 'woocommerce_order_action_send_expedited_email', 'sv_wc_process_order_meta_box_action' );
to make a note with the username of the user doing the action.
