How would you display the contents of an incoming mail?

To display the contents of an incoming email, first, retrieve the email data using an email client or server API, such as IMAP or SMTP. Once the email is fetched, extract key components including the sender, subject, date, and body content. Finally, format this information in a user-friendly way, such as a structured layout in an application or webpage, ensuring that the content is easily readable and accessible.
