WooCommerce doesn't provide the tracking information to your customers automatically.
By default, the tracking links and information are added in the order notes. To be able to forward them to your customers, you need to install an additional plugin to your store.
Here's one that works well with Spreadconnect and is free: Advanced Shipment Tracking - zorem
Once you download and install the plugin, simply head over to the WooCommerce side-menu and click on Shipment Tracking.
Then, under the Shipping Carriers section, you will need to add the shipping carriers we use at Spreadconnect, depending on which countries you send to, which production location you selected for your Spreadconnect account, and the shipping types you offer your customers.
An exhaustive list will be available soon. For now, make sure you select DHL and UPS for Europe, and USPS and FedEx for US. s
