Celaro
Celaro is a code-first email design system that lets teams send all their emails from one platform. Developers build reusable, typed email blocks using React Email and Tailwind CSS, creating a consistent design system for newsletters, onboarding, transactional emails, and more. This approach replaces juggling multiple tools by unifying email creation and sending into a single workflow. Non-technical team members can compose and send emails through an intuitive admin interface with live previews, making collaboration easier. Celaro supports syncing changes instantly via a CLI and offers an API for programmatic email sending, streamlining integration with apps. It targets development teams and marketing professionals who want consistent, scalable email workflows without relying on separate tools for different email types. By combining code-based design with user-friendly composition, Celaro bridges the gap between developers and content creators. The platform also manages audiences and supports various email categories like product updates, notifications, and marketing campaigns. Overall, Celaro simplifies email management by providing a unified system that fits both technical and non-technical users.
