Woocommerce hook not triggering emails for custom statuses - wordpress

Question

I've registered custom order statuses in a plugin I'm working on, but I can't get emails to fire when moving in or out of one of these statuses. (including to/from a core status, ie. the processing/completed emails don't fire when moving from a custom status).
I've registered every possible combination of actions I can think of (excluding on-hold and pending, based on our use case)
Can anyone tell me what I'm missing please?

I welcome any ideas :)

I think you are missing the triggers. Try to hook into woocommerce_order_status_changed action and fire your e-mails as you wish based on $from and $to statuses.
Here's a preview with 3 examples:
function custom_woocommerce_order_status_changed( $order_id, $from, $to, $order ) {
// Get all WC mailer emails
$wc_emails = WC()->mailer()->get_emails();
// Example A: Handle (from) 'my-custom-status' triggers
if( $from == 'my-custom-status' ) {
// Trigger 'completed' e-mail if changing to 'completed'
if( $to == 'completed' ) {
$wc_emails['WC_Email_Customer_Completed_Order']->trigger( $order_id );
}
}
// Example B: Handle (from) 'processing' triggers
if( $from == 'processing' ) {
// Trigger 'my-custom-status' e-mail if changing to 'my-custom-status'
if( $to == 'my-custom-status' ) {
$wc_emails['WC_Email_Customer_My_Custom_Status_Order']->trigger( $order_id );
}
}
// Example C: Handle (to) 'my-custom-status' triggers
// This will fire the email for every order changed to this status (whatever the $from status is)
if( $to == 'my-custom-status' ) {
$wc_emails['WC_Email_Customer_My_Custom_Status_Order']->trigger( $order_id );
}
}
add_action( 'woocommerce_order_status_changed', 'custom_woocommerce_order_status_changed', 20, 4 );
Note: Try to write these conditions as simply and straightforward as you can. Remember that if your order change scenario will be a duplicate, the e-mail will be also triggered (sent) multiple times.
