Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.03431 |
| Opus 5.5 | $0.00026 | $0.01372 |
| Sonnet 5.5 | $0.00013 | $0.00686 |
| Haiku 4.5 | $0.00007 | $0.00343 |
Grade A, and why
react-email scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to react-email — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 401 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Email
Build and send HTML emails using React components. A modern, component-based approach to email development that works across all major email clients.
Installation
npm i react-email
Or scaffold a new project:
npx create-email@latest
cd react-email-starter
npm install
npm run dev
This works with any package manager (npm, yarn, pnpm, bun) — substitute accordingly.
The dev server runs at localhost:3000 with a preview interface for templates in the emails folder.
Adding to an Existing Project
Install the packages and add a script to your package.json:
{
"scripts": {
"email": "email dev --dir emails --port 3000"
}
}
Make sure the path to the emails folder is relative to the base project directory. Ensure tsconfig.json includes proper support for JSX.
Basic Email Template
Create an email component with proper structure using the Tailwind component for styling:
import {
Html,
Head,
Preview,
Body,
Container,
Heading,
Text,
Button,
Tailwind,
pixelBasedPreset
} from 'react-email';
interface WelcomeEmailProps {
name: string;
verificationUrl: string;
}
export default function WelcomeEmail({ name, verificationUrl }: WelcomeEmailProps) {
return (
<Html lang="en">
<Tailwind
config={{
presets: [pixelBasedPreset],
theme: {
extend: {
colors: {
brand: '#007bff',
},
},
},
}}
>
<Head />
<Body className="bg-gray-100 font-sans">
<Preview>Welcome - Verify your email</Preview>
<Container className="max-w-xl mx-auto p-5">
<Heading className="text-2xl text-gray-800">
Welcome!
</Heading>
<Text className="text-base text-gray-800">
Hi {name}, thanks for signing up!
</Text>
<Button
href={verificationUrl}
className="bg-brand text-white px-5 py-3 rounded block text-center no-underline box-border"
>
Verify Email
</Button>
</Container>
</Body>
</Tailwind>
</Html>
);
}
// Preview props for testing
WelcomeEmail.PreviewProps = {
name: 'John Doe',
verificationUrl: 'https://example.com/verify/abc123'
} satisfies WelcomeEmailProps;
export { WelcomeEmail };
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
