MailSpy
MailSpy is a utility for macOS that displays the geographic origin and routing information of emails. It integrates with email clients to show location data and tracking details about message sources, helping users understand the physical origin points of received emails. The app is targeted at email security-conscious users and professionals who want visibility into email metadata and sender location.

1 suggestionNo native Apple Silicon build of MailSpy is currently confirmed — the most recent public information available (December 2020) indicates the app has not been tested on Apple Silicon Macs. Since that time, there has been no widely documented update to a native build. The app continues to run under Rosetta 2 on modern M-series Macs today, but Apple is removing Rosetta 2 in macOS 28 (September 2028), which means an Intel-only version will stop working entirely on that release. Contact the developer at corecode.com to ask whether a native Apple Silicon build is planned or already available but undocumented. If no update is forthcoming, you should begin exploring alternative email security and metadata analysis tools — many email clients now include built-in header inspection and sender verification features that may serve your needs without requiring a separate utility.
