iCloud Mail
mailboxEstablished 2011iCloud Mail is Apple’s privacy-focused communication service, evolved from the legacy .Mac and MobileMe suites. Unlike ad-supported mail providers, it operates on a "privacy-by-default" model, featuring Mail Privacy Protection to block tracking pixels and hide user IP addresses. For subscribers, it offers Hide My Email, a powerful aliasing tool that generates unique, random addresses to keep a user’s primary identity private from third-party sites and newsletters.
