FAQ

Frequently asked questions

Can I render MJML from a JSON string instead of XML?

Yes! The render_mjml tool accepts both raw MJML XML and MJML JSON strings. The engine will automatically detect the format and transpile it into responsive HTML.

What is the maximum size of the generated HTML output?

The integration supports an egress limit of up to 5MB, which is more than enough for even the most complex and content-heavy responsive email templates.

Does the tool validate my MJML syntax during rendering?

Yes, the render_mjml tool uses the official MJML engine which performs validation during the transpilation process to ensure the resulting HTML is compliant with email client best practices.
