Users generally appreciate this WordPress plugin for its ease of use, effectiveness in tracking shipments, and the responsive support team. The plugin simplifies adding tracking information to orders and sending automated emails to customers, enhancing the overall user experience and keeping clients informed about their shipments. Integrations with other tools like TrackShip are praised for improving visibility and order management. However, the plugin's recent updates have drawn criticism for introducing pop-ups that slow down workflow and removing previously free features, now requiring a paid version. Users are frustrated with the degradation of former functionalities and the additional financial burden. Complaints include slower performance, limitations on custom providers, and poor customer communication during these changes.
