Two new functionalities for email templates have been introduced. A 'content' component which provides a container complete with border and padding specifications, and a 'header' component which simply encapsulates its child items. Both use the '@react-email/components' container for layout.
Emails - @kit/email-templates
This package is responsible for managing email templates using the react.email library.
Here you can define email templates using React components and export them as a function that returns the email content.
