TL;DR

Courier orchestrates notifications across channels through providers. Resend sends emails directly with a modern developer experience built on React Email. Resend wins for email-only needs. Courier wins for multi-channel notification routing.

Key Differences

The main things that set these tools apart

Direct vs Orchestrated
Resend wins

Resend sends emails directly with a clean, modern API. Courier routes notifications through providers. For email, Resend is dramatically simpler — integrate in minutes, not hours.

Developer Experience
Resend wins

Resend's React Email integration lets you build emails with React components. TypeScript-first SDK, beautiful documentation. Courier is developer-friendly but focused on routing, not email DX.

Multi-channel
Courier wins

Courier handles push, SMS, Slack, Discord, and in-app alongside email. Resend is email-only. For multi-channel apps, Courier is the only option here.

Total Cost for Email
Resend wins

Resend at $20/month for 50k emails is all-inclusive. Courier requires its own fees plus a separate email provider. For email-only, Resend is cheaper.

Different Problems, Different Tools

The Developer Experience Gap

Resend's React Email integration is a game-changer for React developers — build emails as React components with TypeScript. Courier's developer experience is solid but focused on routing configuration, not email authoring. For email DX, Resend is ahead.

The Sequenzy Alternative
