MailKaro docs

MailKaro is a white-label, drag-and-drop email editor you embed in your product with a few lines of React. Your customers design on-brand emails; you get clean, render-ready HTML back.

The editor ships as one npm package, react-email-craft, with a react-email-editor-compatible API, the same component, props, and ref, so existing code and designs work unchanged. Under the hood it renders the full MailKaro editor, and the server-side renderer turns a saved design into email-safe HTML or MJML.

How it fits together#

• Embed the editor in your app with <EmailEditor /> from react-email-craft. Pass a publishable embed token (pk_live_…) that scopes the plan and enabled features.
• Save the design, a JSON document you store in your own database.
• Render to HTML on your server with email-craft-sdk and send it through whatever ESP you already use.

Nothing paid is ever unlocked in the browser: entitlements are decided server-side from the token, so a missing, invalid, or expired token always falls back to the free editor.

Start here#

• Installation, add the package.
• Quick start, the editor on screen in a few lines.
• Backend integration, wire the server so AI, uploads, and plans light up (secrets stay server-side).
• Unlayer compatibility, existing designs load as-is.
• Elements, every block and its options.

Frequently asked questions#

What is MailKaro?

A white-label, drag-and-drop email editor you embed in your product, plus a server-side renderer that turns a saved design into email-safe HTML or MJML.

Which package do I install?

react-email-craft for React. Vue, Angular and plain JavaScript have vue-email-craft, angular-email-craft and vanilla-email-craft. For rendering on your server, add email-craft-sdk.

Is it compatible with react-email-editor?

Yes. react-email-craft has the same component, props and ref as react-email-editor, and existing Unlayer design JSON is converted when you call loadDesign().

Can the browser unlock paid features on its own?

No. Entitlements are decided on the server from the embed token. A missing, invalid or expired token always falls back to the free editor.
