Launched in July 1996 by Sabeer Bhatia and Jack Smith, Hotmail revolutionized personal communication by making email accessible through a web browser. Before it, email required local clients like Eudora or Outlook Express. Hotmail's architecture, spam filtering evolution, and transition to Windows Live and Outlook.com mirror the broader shift from dial-up to broadband, and from unencrypted SMTP to modern authentication standards.
Researchers, historians, and protocol engineers use this collection to study the evolution of email headers, the rise of automated messaging, early anti-spam mechanisms, and the cultural impact of free webmail on global connectivity.
