1. Install dependencies

Install package from your command line.

npm install @react-email/render -E

2. Create an email using React

Start by building your email template in a .jsx or .tsx file.

import * as React from 'react';
import { Button } from '@react-email/button';
import { Hr } from '@react-email/hr';
import { Html } from '@react-email/html';
import { Text } from '@react-email/text';

export function MyTemplate(props) {
  return (
    <Html lang="en">
      <Text>Some title</Text>
      <Hr />
      <Button href="https://example.com">Click me</Button>

export default MyTemplate;

3. Convert to HTML

Import an existing React component and convert into a HTML string.

You can use the pretty option to beautify the output.
import { MyTemplate } from './email';
import { render } from '@react-email/render';

const html = render(<MyTemplate />, {
  pretty: true,


This will generate the following output:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang="en">
  <p style="font-size:14px;line-height:24px;margin:16px 0">Some title</p>
  <hr style="width:100%;border:none;border-top:1px solid #eaeaea" />
  <a href="https://example.com" target="_blank" style="line-height:100%;text-decoration:none;display:inline-block;max-width:100%;padding:0px 0px">
      <!--[if mso]>
        <i style="letter-spacing: undefinedpx;mso-font-width:-100%;mso-text-raise:0" hidden>&nbsp;</i>
    <span style="max-width:100%;display:inline-block;line-height:120%;text-decoration:none;text-transform:none;mso-padding-alt:0px;mso-text-raise:0">Click me</span>
      <!--[if mso]>
        <i style="letter-spacing: undefinedpx;mso-font-width:-100%" hidden>&nbsp;</i>

4. Convert to Plain Text

Plain text versions of emails are important because they ensure that the message can be read by the recipient even if they are unable to view the HTML version of the email.

This is important because not all email clients and devices can display HTML email, and some recipients may have chosen to disable HTML email for security or accessibility reasons.

Here’s how to convert a React component into plain text.

import { MyTemplate } from './email';
import { render } from '@react-email/render';

const text = render(<MyTemplate />, {
  plainText: true,


This will generate the following output:

Some title


Click me [https://example.com]

html-to-text options used for rendering


If you are using NextJS with the render function, be aware that with Next 14 or above you might have errors using it.

So it is recommended that you use the renderAsync variant of this function. It has the same API but uses different underlying React functions to avoid problems like these.
