What does Courier do?
Courier is a platform built for product and engineering teams to handle customer messaging. It provides the infrastructure to design, send, and track notifications across every channel—like email, SMS, push notifications, and Slack—directly from your application. Instead of building and maintaining separate systems for each type of message, teams use Courier's APIs and tools to manage everything in one place.
The platform works by connecting to your product's data, allowing you to trigger personalized messages based on user actions. Its core components include a notification infrastructure with APIs and SDKs, a visual Design Studio for creating templates without code, and a feature called Inbox for embedding a notification center into your app. A key benefit is its integration network, which connects to over 50 providers like SendGrid and Twilio, letting you switch services without rewriting your code.
This tool is most useful for software companies that need reliable, scalable messaging for their users. Development teams use it to offload the complexity of notification systems, while product and growth teams use it to launch lifecycle campaigns or user journeys. Real-world applications include sending password reset emails, coordinating multi-step onboarding sequences, and providing users with a central hub for all their app alerts.
