The CLOUD Act (Clarifying Lawful Overseas Use of Data Act) is a 2018 US law that lets US authorities compel US-based technology and cloud providers to hand over data they control, regardless of whether that data is stored inside or outside the United States. For businesses subject to the GDPR, the CLOUD Act is the main reason the physical location of a US provider's servers does not, by itself, remove US legal reach over their data.
How the CLOUD Act works
The CLOUD Act applies to companies under US jurisdiction, not to a geographic region. A US-headquartered provider can store European customer data in a Frankfurt or Dublin data center and still be required to disclose it under a valid US legal request. An "EU region" setting changes where the data sits, not which government can compel access to it.
Why the CLOUD Act matters for email marketing
If your subscriber list holds financial, health, or legal data, CLOUD Act exposure is a real compliance factor. It is why many organizations choose a provider outside US jurisdiction. Mailpro is Swiss-hosted and Swiss-run, so customer data in Geneva sits outside the CLOUD Act's reach. See our guide to the best GDPR-compliant email marketing software and email marketing not hosted in the USA, or the related terms Standard Contractual Clauses, EU adequacy decision, and GDPR.
