Studio SDK Startup at $200 bills $600 with the extra sessions, and Business at $2,000 includes 50,000 sessions.

Building your own email editor on GrapesJS.

The framework is free, and the editor around it is a project your team starts and then keeps running.

What the framework gives you

GrapesJS is free under BSD-3 and ships the canvas, blocks, storage hooks and an MJML plugin. The editor UI is yours.

What your team builds and keeps

Template storage, image hosting, merge tags, previews, a test send and inbox testing are yours. Upgrades and patches stay with you.

What embedding saved

Affinect saved five developer-months by embedding Topol Plugin. CustomerScore.io saved three months of initial development time.

Mautic built its email builder on GrapesJS between 2019 and 2021 and called it over a year of community work. Its builder bundle has 527 commits. Its launch note listed MJML head components that did not render.

Will the emails look right in every inbox?

Your users hit send, and the email has to hold up in Outlook 2016 and in Gmail.

90+ email clients

Templates compile through MJML to HTML that renders correctly in 90+ email clients, old Outlook included. Topol tests the output itself.

Preview before sending

Topol Plugin builds in desktop, mobile and dark-mode previews with merge-tag data. Studio SDK switches between device widths while editing.

How Studio SDK renders

Studio SDK compiles MJML in the browser through an open-source plugin. Its docs call the output compatible with most email clients.

How does integration work?

Install a package, mount the editor with your key, and emails render in your app.

Your framework

Install Topol's package for React, Vue, Angular, Svelte or plain JavaScript. Studio SDK ships a React component and plain JavaScript.

Your storage

Topol Plugin hosts images or uses your bucket from $140. Studio SDK uses its cloud or your callbacks on every plan.

Your backend

Topol Plugin saves to your endpoints and returns HTML by API. Studio SDK saves through callbacks and exports in the browser.

What does GrapesJS have that Topol Plugin does not?

GrapesJS has these three, so check which ones your product needs.

An open-source framework

GrapesJS is free under BSD-3 with 26,000 GitHub stars. Topol Plugin is a commercial editor, and MJML underneath it is open source.

Web pages and documents in one editor

Studio SDK builds websites, emails and documents from one package. Topol Plugin builds emails and landing pages.

Full control of the editor UI

Studio SDK lets you rebuild every panel without a cross-origin iframe. Topol Plugin runs in an iframe with custom themes and blocks.

How to migrate from GrapesJS to Topol Plugin.

Both editors run side by side behind a flag until your last GrapesJS tenant has moved over.

  1. Export your templates as HTML

    Run the Studio SDK project files command, or export HTML from the framework's editor.

  2. Convert HTML to Topol JSON

    Run Topol's conversion handout on the HTML, or drop one template into an HTML block.

  3. Install the package, swap the script

    Replace @grapesjs/studio-sdk or grapesjs with Topol's package for your framework, then load your JSON.

  4. Map your configuration

    Map data-source variables, conditions and collections to merge tags, display conditions and loop blocks, and rebuild custom components as custom blocks.

  5. Run both behind a flag

    Move one tenant first, then the rest, while your GrapesJS templates keep working.

Rough timeline: you have a sandbox on day one and a first tenant within a week, then move the rest over the following two weeks.

Need sending too? Lettr by Topol sends it.

Lettr, Topol's EU-hosted email API and SMTP, sends what your users build in the editor. GrapesJS Studio SDK exports email HTML and MJML, and sending through your own backend is yours to arrange.

GrapesJS vs Topol Plugin: which one fits your team?

Choose GrapesJS Studio SDK if.

  • You want the open-source GrapesJS framework and will build the editor yourself.
