About Courier

Courier is the fastest way for developers to build notifications for their app. Our APIs take the tedium out of integrating various notification channels, while our visual designer lets anyone design a message template and deliver their notifications to the best channel for each user with a single API call. Email, Push, In-App, Slack, SMS, you name it. Think "Stripe, for notifications."
