Pros

    Courier

    Courier is notification infrastructure for customer messaging, built for humans and AI agents. It sits between your app and every channel you send on: email, SMS, push, in-app inbox, chat, and webhooks. You send one request, and Courier works out where it goes, what it looks like, and whether the user wanted it at all. Teams use it for the messages a product has to send: onboarding, alerts, receipts, reminders, and account notices. You keep the providers you already pay for. Courier is the layer above them.
