What are some good email styling node libraries?

I am using node, express, and apollo graphql on backend. Sending beautiful emails is one of the core features of the project. Any recommendations on good node styling libraries would be really helpful.

Do you need to go low-level? Otherwise MailChimp has an API.

I don't think there's anything that's related to Node in this case. Styling is done with CSS. So I'd rather use or (more people choose MJML because it's easy)
