📣 How Twilio Used Courier to Unify Notifications for 10 Million Developers

Twilio powers communication for over 10 million developers and 300,000 businesses worldwide. As a leader in customer engagement, they’ve set the standard for seamless, scalable developer tools. But as their business grew, managing notifications became a challenge. Fragmented tools and workflows created inconsistencies and inefficiencies across teams. To solve this, Twilio turned to Courier—a platform designed to unify notifications and improve the developer experience at scale.

Twilio’s Challenge: Scaling In-Console Messaging

Twilio’s in-console notifications are critical for keeping developers informed. Whether it’s product updates, feature launches, or system alerts, notifications help developers stay engaged and take action. But as Twilio scaled, teams started relying on different tools to manage notifications. The result? Fragmented user experiences, messaging inconsistencies, and time lost managing workflows.

For a platform of Twilio’s scale, these challenges added friction to what should have been a seamless experience. They needed a unified solution to deliver consistent, real-time updates while simplifying workflows for their teams.
