We’re excited to launch Courier Create, a flexible toolkit designed to make template and brand editing effortless in multi-tenant environments. Built for React applications, Courier Create enables seamless integration of embeddable editors that empower teams to personalize email templates and manage branding directly within your app.
With full support for tenant-specific configurations, Courier Create allows each client to maintain distinct logos, colors, and styles, without needing to leave your platform. JWT authentication will give developers complete control over user access and publishing workflows, while auto-save and custom theming options make the editor experience sleek and efficient.
Developers can enable the Template Editor and Brand Editor individually or use them together in a unified interface. From variable-driven personalization to custom save logic and visual theming, Courier Create offers all the tools needed to deliver dynamic, branded email experiences at scale.
Whether you're modernizing your notification infrastructure or building a white labeled communications platform, Courier Create brings the speed, flexibility, and customization today's teams need.
