Embeddable Designer
Courier Create is a powerful template editing solution tailored for multi-tenant React applications. With built-in support for tenant-specific configurations and real-time editing capabilities, Courier Create helps streamline the design and deployment of email templates directly within your app’s interface. Embed Courier Create directly into your React application via the @trycourier/react-designer package. Courier Create’s flexible theming options, and JWT-based authentication allow teams to maintain control over the editing workflow while ensuring security and consistency across multiple tenants. Users can personalize both templates and brand settings using a unified interface that supports advanced features like variable substitution, custom theming, auto-save toggling, and publishing hooks. Whether you’re launching new communications or updating tenant-specific branding, Courier Create offers the tools you need to efficiently manage content across clients without compromising on design flexibility or performance.

Key Courier-Create Features

  • Embedded React Integration - Easily embed the template and brand editors directly into your existing React application using the @trycourier/react-designer package.
  • Multi-Tenant Support - Seamlessly manage templates and branding for multiple tenants, with individualized configurations and access controls.
  • Embedded Template Editor - Create and edit dynamic, personalized templates using a drag-and-drop interface, with support for nested variables and live preview.
  • Brand Editor - Modify tenant-specific branding elements such as logos, colors, and layout styles directly within your app.
  • JWT Authentication - Secure access to editing tools via granular JWT scopes, supporting both full and tenant-specific permissions.
  • Email Channel Support - Fully supports email template editing with future support planned for additional channels like SMS and push.
  • Channel Restriction - Restrict which channels are visible in the editor using the routing.channels prop, perfect for email-only or channel-specific workflows.

Subscription Topics

Tenant-scoped templates created through Courier Create do not currently support assigning a subscription topic directly in the editor UI. If your application uses subscription topics to enforce user notification preferences, you can associate a topic at send time by including it in the /send payload: 
{
  "message": {
    "template": "TENANT_TEMPLATE_ID",
    "to": { "user_id": "user-123" },
    "routing": { "method": "single", "channels": ["email"] },
    "metadata": { "tenant_id": "tenant-abc" },
    "preferences": {
      "subscription_topic_id": "order-updates"
    }
  }
}
When preferences.subscription_topic_id is present, Courier enforces the user’s preference for that topic before delivering the message — the same behavior as templates with a topic assigned in the Studio UI.
