- A map shows ~2,100 Swiss municipalities and their official email providers, grouped by jurisdiction.
- US-based providers are subject to the US CLOUD Act, allowing US authorities to access stored data regardless of location.
- Each municipality's official domain is checked via public DNS records (MX + SPF) and classified by provider type.
- DNS records indicate mail routing and authorized senders, not necessarily data storage locations.
- The code and data are available on GitHub, and users can report errors by submitting an issue.
