Can I use it to inline CSS for an email?

What conversions does this tool include?

Inline to CSS classes, CSS classes to inline, CSS properties to CSS variables, CSS variables to properties, minify CSS, beautify CSS, HTML to JSX/React, and CSS to Tailwind.

What is converting HTML to JSX useful for?

For quickly turning existing HTML markup into the syntax React uses (JSX), adjusting attributes like class to className.
