Courier — $500 in credits for Startups

Deal Highlights

What Is Courier?

Courier is the notification orchestration platform that designs, routes, and delivers notifications across email, push, SMS, Slack, in-app, and any other channel — from a single API. Instead of building separate notification logic for each channel (SendGrid for email, Twilio for SMS, Firebase for push), Courier provides one API that handles routing, templates, preferences, and delivery tracking across all channels.

For startups building products with multi-channel notifications, Courier replaces the custom notification infrastructure that typically takes 4–8 weeks to build and ongoing maintenance to keep reliable.

Key Features for Startups

One API, Every Channel

Send a notification via courier.send() with the user ID and template ID. Courier determines which channels the user prefers, renders the template for each channel, and delivers across email, push, SMS, Slack, or in-app. Adding a new channel is a configuration change in Courier — not a code change in your application.

User Preference Management

Courier provides a hosted preference center where users choose: "I want order updates via email and push, but marketing updates only via email." Your application does not manage per-user notification preferences — Courier handles it.

Intelligent Routing

Define routing rules: "Send via push notification. If not read in 30 minutes, send email. If email not opened in 2 hours, send SMS." This escalation logic ensures important notifications reach users without spamming every channel simultaneously.

Courier vs Custom Notification System

Tips to Maximize Your Courier Credits

1. Start with email + in-app — These two channels cover 90% of notification needs. Add push and SMS when you have mobile users.
2. Implement user preferences from day one — Users who control their notification channels have lower unsubscribe rates and higher engagement.
3. Use routing for critical notifications — Order confirmations, security alerts, and payment failures should escalate across channels until acknowledged.
4. Abstract your notification logic — Use Courier as the only notification API in your code. When you switch email providers (SendGrid → Resend), the change happens in Courier — not in your application.
5. Track delivery metrics — Monitor delivery rates, open rates, and failure rates per channel and per notification type. Low delivery on a channel indicates a configuration issue.
