# Email and order notes

> WooCommerce order notes and customer email behavior.

## Order notes

The plugin adds structured order notes for:

* Awaiting payment (at checkout redirect)
* Payment received (on `invoice.paid`)
* Expired, cancelled, failed, underpaid, refunded events

Status change notes are suppressed during webhook processing to avoid duplicate WooCommerce system notes.

## Customer emails

WooCommerce sends standard order emails based on status transitions:

* **On-hold** email when redirected to Meum checkout
* **Processing** email when `payment_complete()` is called on `invoice.paid`

Email behavior follows WooCommerce core rules for your store configuration.
