# Delivery Status Definitions

Open Letter Connect provides real-time delivery tracking using data from USPS and our delivery partners like Accuzip. This tracking shows the status of each mail piece through printing, USPS handoff, sorting, transit, and delivery.

Accurate tracking helps you monitor your mail’s progress and spot any issues such as delays or returns. Understanding each delivery status and USPS scanning process allows you to interpret tracking data correctly and set realistic delivery expectations.

* **Scheduled**\
  Your mailing order is queued and scheduled for processing based on USPS batch timing.
* **Processing**\
  The order is being prepared for printing and mailing. Address verification and print proofs occur in this stage.
* **Mailed**\
  Mail pieces have been printed and handed off to USPS for delivery.
* **Expected Delivery Date**\
  The estimated date USPS expects the mailpieces to reach recipients, based on standard delivery timelines.
* **Completed**\
  Delivery tracking is complete, and all mail pieces have reached their final status.

#### Tracking Analytics Statuses

* **Returned to Sender (%)**\
  Mailpieces that USPS has returned due to undeliverable addresses or refusals.
