Code-First CMS For Newsletters

The CMS for
Newsletters

Code blocks with React EmailReact Email and Tailwind CSSTailwind CSSand build your newsletters in an admin interface.

Why we built Celaro

You code the blocksand your team sends the newsletters

We built Celaro because shipping newsletters meant choosing between two bad options. Developer-heavy tools created bottlenecks. Marketing-heavy tools led to broken formatting and inconsistent designs. We fix this by bringing the CMS experience to newsletters.
