2. [Dentling (commenter)]: For this reporter the error came from importing `Tailwind` from `@react-email/tailwind` instead of `@react-email/components` - the tailwind package pulled client-side code into the email template, and Next 13.5 flagged it as a React Server Component importing react-dom/server. Removing the separate @react-email/tailwind import fixed it. (No maintainer verdict in thread.)
