React doesn't do its own styling though, and since email will not run js, you are basically talking about css at this point

Maybe that is the secret sauce of this service. They render the email with react and automagically convert that to something that works for email?

I think they literally just use React as a templating language, basically. You write React components and this service renders them down to email-friend HTML. Like SSR but for email.
