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 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.
Twilio needed a notification platform that could scale with them and adapt to their complex workflows. Courier stood out for its ability to centralize notifications and streamline delivery across channels. Key factors in their decision included:
With Courier, Twilio could unify their notifications while enhancing the experience for developers.
Integrating Courier gave Twilio the tools to fix fragmented workflows and deliver better notifications across their ecosystem. With Courier’s web inbox, Twilio created a central hub for real-time, in-console updates that developers could rely on. Notifications were now consistent, actionable, and delivered exactly when needed.
Courier’s notification center also allowed Twilio to give developers control over their preferences, including digest schedules and message frequency. Customizable templates ensured that every notification matched Twilio’s branding, while real-time delivery powered by webhooks and WebSockets kept developers in sync.
By streamlining their workflows and centralizing notifications, Twilio saved engineering time and created a better experience for their developer community.
The integration with Courier brought immediate and measurable improvements:
These changes didn’t just address the challenges Twilio was facing—they elevated the experience for developers and reinforced Twilio’s reputation for delivering world-class tools.
The partnership with Courier helped Twilio transform how they manage notifications. Developers now have a consistent and intuitive in-console experience, making it easier to stay informed and take action. By centralizing notifications and improving real-time delivery, Twilio increased engagement and reduced friction for its users.
Internally, the benefits were equally clear. Engineering teams saved time by eliminating fragmented workflows, while Courier’s customizable templates ensured consistent branding without additional effort.
Twilio’s Product Lead, Kandyce Knight, summed it up: “We at Twilio know how important it is to meet your customers at their preferred channels. Courier gives us the power to fully personalize our customer touchpoints in one easy-to-use, centralized tool.”

Top Platforms for Preference Management in 2025
73% of users unsubscribe from poorly targeted notifications. The problem: preference logic is scattered across marketing platforms, product notification systems, and multiple providers that don't talk to each other. Most preference tools handle marketing OR product notifications, not both. This guide compares 9 platforms for 2025, evaluating integration depth, compliance support (GDPR, CAN-SPAM, TCPA), and multi-channel capabilities across email, SMS, push, chat, and in-app. Includes SDK references, implementation examples, and MCP setup for AI-assisted configuration. Best for teams planning Q1 notification infrastructure improvements.

Toasts caught a lot of heat after GitHub removed them for accessibility reasons. But most products aren’t GitHub. With a proper notification center, toasts can still earn their place.
