Render an email

​

Returns email-ready HTML. Use this endpoint to inspect your compiled markup.

Liquid tags are left intact—{{customer.first_name}} stays in the output as written. To evaluate liquid against real profile data instead, use Preview an email.

The render, preview, review, link, and publish endpoints share a rate limit of 5 requests per second per workspace.

Path Parameters
  • id
    Type: string Format: uuid
    required

    The UUID of the email. If your email has translations, this is the ID of a specific language variant.
