# An introduction to ClearSend®
## This article will explain what ClearSend® is, how it works, and how to access the postage data.
### **What is ClearSend®?**
### 
ClearSend® gives you certified proof of postage and tracking through the Royal Mail network, at no extra cost.
This means, in addition to tracking your letter through Postworks process, you can now see where your letter is in the Royal Mail network.
Postworks is the *only provider* to offer this certified proof of postage.
### **How does it work?**
Postworks has developed technology that extracts the address from a document and analyses it against 28 million addresses in the UK, to match it against one. In less than 250 milliseconds.
A barcode is created that connects to Royal Mail's delivery network, giving you unprecedented visibility of letters. Ambiguity about whether an item has been handled by Royal Mail will be removed.
### **How can I get access to ClearSend® data?**
ClearSend® is available to users on our Enterprise plan or above. If you're on this plan, you don't need to do anything differently.
Log in to the [Postworks Portal](https://hub.postworks.co.uk) as normal and you will see the ClearSend data populated in the data tables under Post Items.
### What qualifies for ClearSend**®** tracking?
ClearSend® tracking is currently available for both **1st Class** and **2nd Class** items. If you’re sending mail via either of these services, tracking data will be available through ClearSend®.
Royal Mail typically takes 2–3 days to report postage data back to us. If tracking information isn’t visible immediately, please allow a few days for it to appear.
