How to create an email app with TinyMCE Cloud

How-to Use TinyMCE

TinyMCE’s rich text editing capabilities have earned the trust of over 1.5 million developers. And if you’re building a platform to help design that irresistible email, you can quickly get TinyMCE up and running with TinyMCE Cloud.

This article explains Tiny Cloud for email app developers – using an email marketing software demo, it demonstrates how to get started including TinyMCE as your text editor.

It’s important to note that like other rich text editors, TinyMCE doesn’t provide the drag-and-drop functionality that many email builders employ – rather, it provides the rich text editing capabilities you would find within the builder.

What you need to get started

First get your API key:

When you sign up for an account, and get your API key, you have 14 days FREE access to TinyMCE premium plugins. The free access activates when you use the key in your editor, and load it into a browser with premium plugins configured in the tiny.init script.

If you don’t have an API key or a TinyMCE account, you cannot access Premium Plugins, and the text area produces a warning message:

This domain is not registered with Tiny Cloud.  Please see the quick start guide or create an account

Using your API key, and registering your application’s URL, prevents these messages popping up in the text area.

How to start adding Tiny Cloud to your email app

These instructions show how to make a demo with TinyMCE from the cloud, using our purpose-built email starter config. It contains all of the plugins and features common to any market-leading email builder platform.

The demo contains three instances of TinyMCE, one for each rich text block. It’s meant to simulate how an email builder might layout an email. You can add as many instances as you like to your email builder without worrying about conflicts or errors (as mentioned, drag-and-drop functionality found in email builders is outside TinyMCE scope.)

This demo uses TinyMCE inline mode, and uses more than one text editor on the email app page.

Inline mode allows for the text editor to work with different HTML elements on a page, and keeps the toolbar hidden until it’s needed.

Configure the API key:

  1. Log into your account, and scroll down to the TinyMCE Installation heading. Copy the HTML starter code.
  2. Create an index.html file
  3. Paste the config into your new file:
<!DOCTYPE html>
  <script src="" referrerpolicy="origin"></script>
    Welcome to TinyMCE!
      selector: 'textarea',
      plugins: 'advlist autolink lists link image charmap preview anchor pagebreak',
      toolbar_mode: 'floating',

Reconfigure the TinyMCE script

  1. Navigate to the email editor product page and copy the config.
  2. Paste the email app config (minus the surrounding HTML elements) in place of the <script> tags containing the default tinymce.init script copied from your account.
        var tokens = [
            { text: "name.first", value: "{{name.first}}" },
            { text: "name.last", value: "{{name.last}}" },
            { text: "name.full", value: "{{name.full}}" },
            { text: "email.home", value: "{{email.home}}" },
            { text: "", value: "{{}}" },

            inline: true,
            plugins: 'link lists image emoticons advcode editimage linkchecker powerpaste',
            toolbar: 'styles | bold italic forecolor backcolor link image emoticons tokens | align bullist numlist | code removeformat',
            menubar: false,
            link_target_list: false,
            object_resizing : false,
            formats: {
                h1: { block: 'h1', styles: { fontSize: '24px', color: '#335dff' } },
                h2: { block: 'h2', styles: { fontSize: '18px' } },
                calltoaction: { selector: 'a', styles: { backgroundColor: '#335dff', padding: '12px 16px', color: '#ffffff', borderRadius: '4px', textDecoration: 'none', display: 'inline-block'} }
            style_formats: [
                { title: 'Paragraph', format: 'p' },
                { title: 'Heading 1', format: 'h1' },
                { title: 'Heading 2', format: 'h2' },
                { title: 'Button styles'},
                { title: 'Call-to-action', format: 'calltoaction' },
            placeholder: "Write here...",
            toolbar_mode: "wrap",
            noneditable_regexp: /\{\{[^\}]+\}\}/g,
            setup: (editor) => {
                editor.ui.registry.addIcon('token', '<svg enable-background="new 0 0 24 24" height="24" viewBox="0 0 24 24" width="24" xmlns="<a href=""></a>"><path d="m0 0h24v24h-24z" fill="none"/><path d="m21 12-4.37 6.16c-.37.52-.98.84-1.63.84h-3v-2h3l3.55-5-3.55-5h-10v3h-2v-3c0-1.1.9-2 2-2h10c.65 0 1.26.31 1.63.84zm-11 3h-3v-3h-2v3h-3v2h3v3h2v-3h3z"/></svg>');
                editor.ui.registry.addMenuButton("tokens", {
                    icon: "token",
                    tooltip: "Insert token",
                    fetch: (callback) => {
                        var items = => {
                            return {
                                type: "menuitem",
                                text: token.text,
                                onAction: () => {

Add email app styling

  1. Create space after the script tags with the tinymce.init, and paste the following CSS content to style the email app:
    body {
        padding: 0;
        margin: 0;
        box-sizing: border-box;


    .container {
       background-color: #f9f9fb;
       margin: 0 auto;
       max-width: 1000px;

    .email {
       max-width: 840px;
       margin: auto;

    .toolbar {
       background-color: #fff;
       height: 42px;
       padding-top: 48px;
       border-bottom: 1px solid rgba(0, 0, 0, .1);

    .tinymce:focus {
       border-radius: 0.5px;
       box-shadow: 0 0 0 4px #fff, 0 0 0 7px #99afff;
       outline: 0;

    .mceNonEditable {
       background-color: #e7ecff;
       padding: 1px 0;
       color: #4059b3;
       font-family: SFMono-Regular, Menlo, Monaco, Consolas, "Liberation Mono", "Courier New", monospace;
            font-size: 0.9375em;
  1. Update the HTML content with the demo email editor app HTML:


    <div class="container">
    <div class="toolbar"></div>
    <div class="email">
        <table style="background-color: #f9f9fb; width: 100%; padding: 32px 0" border="0">
                <td align="center">
                    <table border="0" width="100%" style="max-width: 660px; width: 100%; background-color: #ffffff; border: 2px solid #dfe3ec; border-radius: 8px; overflow: hidden" cellpadding="0" cellspacing="0">
                            <td style="padding: 16px 64px 0;">
                                <div class="tinymce" style="font-family: 'helvetica', sans-serif; color: #243376; font-size: 16px; line-height: 1.5;">
