Agentic-first email builder: a typed document model, an operations API for LLM agents, a dependency-light HTML renderer, and a modern React editor.
AI is great at writing emails and bad at writing email HTML. Email Builder lets models and people edit the same structured document through the same validated operations, and leaves the HTML to a renderer that knows Outlook.
@usewaypoint/email-builder) designs convert with one call.npm install @maildun/email-builder
Edit with the React editor:
import { EmailEditor } from '@maildun/email-builder/editor';
import '@maildun/email-builder/styles.css';
export function Compose() {
return (
<div style={{ height: '100vh' }}>
<EmailEditor defaultValue={design} onChange={save} />
</div>
);
}
Render the stored JSON anywhere:
import { renderEmail } from '@maildun/email-builder';
const { html, text, warnings } = renderEmail(design);
Generate with any LLM:
import { buildSystemPrompt, createAgentSession, runTool, toAnthropicTools } from '@maildun/email-builder/agent';
const session = createAgentSession(design);
// system: buildSystemPrompt(), tools: toAnthropicTools(session.tools)
// for each tool call: runTool(session.tools, call.name, call.input)
session.getDocument(); // the new design
Connect an AI client over MCP:
