  • Automated SMS Notifications for a Courier Service

    Automated SMS Notifications for a Courier Service

    Project Overview

    We developed an effective automation for one of the leading courier companies, utilizing Microsoft Power Automate to streamline SMS notifications about shipment status. The solution enables automatic alerts at key delivery stages, reducing the need for manual status updates.

    Challenges & Solutions

    Customers frequently inquired about the progress of their shipments, creating additional workload for the support team. By implementing an automated workflow in Power Automate, we integrated SMS notifications directly with the company’s tracking system, ensuring timely and reliable updates.

    Tech Stack

    • Automation: Microsoft Power Automate
    • Messaging Service: Twilio, SMS gateways
    • Integration: API connections with courier tracking systems

    Outcome

    The automation significantly improved customer communication, reduced the burden on support teams, and ensured that customers received timely updates without additional effort from courier staff.
