Twilio, a leading customer engagement platform, was facing challenges in managing notifications as its business grew, resulting in fragmented tools and workflows that 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. By centralizing notifications and streamlining delivery across channels, Twilio was able to deliver consistent, real-time updates while simplifying workflows for its teams. The integration with Courier brought immediate and measurable improvements, including increased engagement and reduced friction for developers, as well as internal benefits such as saving engineering time and ensuring consistent branding without additional effort.
