♻️ Change the mail app #1096
Description
Problem
The current implementation in src/mail is not optimal for integrating the Cunningham theme or for maintaining scalable, modern HTML emails.
Proposal
Adopt react.email for generating email templates as React components. This approach will:
Allow us to build reusable, themeable email components.
Make it easier to maintain visual consistency with the Cunningham theme and other UI updates.
Enable leveraging TypeScript and modern React patterns for better developer experience and reliability.
This package is used by Blocknote (https://www.blocknotejs.org/docs/editor-api/export-to-email) as well.
