This plugin connects a WooCommerce store to the USPS tracking API to automatically update order statuses and notify customers. It is designed for store owners who ship with USPS and want to reduce manual order management while improving customer communication.

Automatic Status Updates: The plugin queries the USPS API hourly. It changes order statuses to reflect key shipping stages like 'in transit' and marks orders as complete upon delivery.

Customer Email Notifications: Three new email types are added to the store. Customers automatically receive notifications when their order is dispatched, out for delivery, and has been delivered.

Handles Multiple Packages: If an order has several tracking numbers, the plugin intelligently manages the overall order status. It updates to 'completed' only when all packages are reported as delivered.

Custom Order Statuses: Introduces specific statuses such as 'packing complete' and 'in transit' to provide a more detailed view of the fulfillment process within the admin dashboard.

Developer Actions: Fires a custom action on each shipping status change, allowing developers to hook in other systems, like sending mobile push notifications, for further automation.
