Courier is a platform that makes it fast and easy to build a notifications system. Product and engineering teams need template management, custom routing, detailed logs, automated workflows, and other internal tools to run critical operations. Rather than build from scratch, developers can use Courier to build a powerful notifications infrastructure, faster. Our notifications designer includes drag-and-drop building blocks so you can assemble a notification in minutes. From there, you can write custom code, connect to data sources, or add additional channels such as email, chat, in-app, SMS, and push to create dynamic notifications your users will love. Thousands of companies like LaunchDarkly, Contentful, Lattice, Vanta, and ApartmentList use Courier to power their notifications that drive faster operations and better engagement.
