How to convert MJML markup to HTML with your AI

Connect your agent to MJML once. From there, you can pass markup strings directly to your AI to get clean, responsive code.

Short answer

How do I turn MJML into HTML using AI?

You provide your MJML XML or JSON strings to your agent, which then uses the render tool to generate the final HTML. You'll get responsive, production-ready code ready for your email service provider.

Where every output lands.

The results of your conversion

Your agent handles the heavy lifting of the markup translation.

CODE

Ready to use HTML

The tool generates the full HTML markup from your MJML input. You get code that is ready to drop into an email template.

VALIDATION

Clean markup output

The conversion process ensures the resulting HTML follows standard email client requirements. This reduces the chance of broken layouts.

REVISION

Human review needed

You should check the final HTML in a test inbox. The AI handles the conversion, but you decide if the visual layout meets your specific needs.

REUSE

JSON or XML support

Whether you work with JSON or XML strings, the agent processes both formats. You get consistent HTML regardless of your source format.

The workflow

What your AI does when the markup arrives.

The agent acts as a bridge between your markup language and the final email code.

  1. Receive markup

    Your agent accepts the MJML string you provide in the chat, whether it's in XML or JSON format.

    render_mjml

  2. Process conversion

    The agent runs the markup through the rendering engine to translate the MJML logic into HTML tags.

    render_mjml

  3. Generate code

    The tool produces a complete, responsive HTML block based on the instructions in your MJML.

    render_mjml

  4. Deliver output

    The agent presents the finished HTML code block directly in your chat interface.

FAQ

How this task behaves.

  • 01

    Can the AI edit the actual MJML file for me?

    No. The tool converts existing markup into HTML. It does not have the capability to modify or save changes back to your original MJML files.

  • 02

    Does it support both JSON and XML formats?

    Yes. The agent can process MJML provided as either a JSON string or an XML string.

  • 03

    Will the AI design the email from scratch?

    No. You must provide the MJML markup. The AI uses the provided markup to generate the HTML; it does not invent new email designs without input.

  • 04

    Is the output responsive?

    Yes. The conversion process is designed to produce responsive HTML that works across different email clients.

  • 05

    Can the AI upload the HTML to my ESP?

    No. The tool only generates the HTML code. You are responsible for copying that code and uploading it to your email service provider.
