The CMS for
Newsletters

newsletters in a simple admin interface.

Typed blocks in your codebase

Code-First
For Developers

Build blocks in code right from your IDE.

Typed blocks
Define structure in code with full type safety and validation before send.
Reusable content
Ship consistent layouts while editors work from shared block libraries.
One source of truth
Update blocks once; every campaign inherits the same behavior and styling.

Visual editing for your team

Let your team focus on content, not code.

Visual editing
Arrange and tune content in a focused admin, without touching markup or deploys.
Content-led workflow
Write copy and fill block fields; structure and safety stay defined in the codebase.
Consistent quality
Reusable blocks keep layouts on-brand and reduce last-minute design surprises.
