While the result may not be identical to your original MJML, it can provide a solid starting point, saving you significant time in recreating your email template.

What else you can try:

Generating API Documentation

Clear and comprehensive API documentation is crucial for any web project. Sonnet can help you create or improve your API docs.

Example Prompt:

I have a REST API for a user management system with endpoints for user registration, login, profile update, and deletion. Can you generate OpenAPI (Swagger) documentation for these endpoints? Include sample request and response bodies.        

Sonnet can provide you with a structured OpenAPI specification that you can further customize and integrate into your project.

Creating Database Schemas

When designing a new database or updating an existing one, Sonnet can assist in creating schema definitions.

Example Prompt:

I'm building a blog application and need a database schema. The main entities are Users, Posts, Comments, and Categories. Can you create SQL statements to define these tables with appropriate fields and relationships? Use PostgreSQL syntax.        

This will give you a starting point for your database structure, which you can then refine based on your specific requirements.

Optimizing Performance

Sonnet can provide suggestions for improving the performance of your web applications.

Example Prompt:

I have a React application that's loading slowly. Here's a snippet of my main component: [Paste your component code] Can you suggest ways to optimize this component for better performance? Consider things like unnecessary re-renders, expensive computations, or inefficient data fetching.        

Sonnet can analyze your code and provide specific suggestions for improvement, potentially helping you identify issues you might have overlooked.

Accessibility Auditing

Ensuring your web applications are accessible is crucial. Sonnet can help audit your code for accessibility issues.

Example Prompt:
