EU data sovereignty & regulatory compliance

Why data sovereignty matters for email processing

Inbound email is one of the most sensitive data flows in any organisation. Invoices, contracts, customer complaints, HR correspondence, legal notices — all of it arrives via email. Where that data is processed and who has legal authority over it is a material business risk.

The U.S. jurisdiction problem

Most email processing services are operated by U.S. companies or use U.S.-owned cloud infrastructure. This creates exposure to several U.S. laws that directly conflict with EU data protection:

CLOUD Act (2018)

The Clarifying Lawful Overseas Use of Data Act allows U.S. law enforcement to compel U.S.-based companies to hand over data stored anywhere in the world — including EU data centres. A DPA with a U.S.-owned processor cannot override this.

FISA Section 702

The Foreign Intelligence Surveillance Act allows U.S. intelligence agencies to collect data from non-U.S. persons through U.S. technology companies. This surveillance operates without individual warrants and can encompass email content.

Patriot Act

Grants broad authority for U.S. government agencies to access business records held by U.S. companies, including data stored in EU locations.

The practical impact

The Schrems II ruling (2020) invalidated the EU-U.S. Privacy Shield precisely because of these conflicts. The EU Court of Justice found that U.S. surveillance laws provide insufficient protection for EU personal data. This legal uncertainty affects any organisation using U.S.-owned email infrastructure.

How EmailConnect ensures sovereignty

EmailConnect is designed from the ground up to eliminate U.S. jurisdictional exposure:

EU-owned company

EmailConnect is owned and operated by an EU entity. No U.S. parent company, no U.S. investors with board control, no U.S. legal obligations.

EU-only infrastructure

All servers, databases, and storage are located in EU data centres (Germany and the Netherlands), operated by EU-headquartered providers. No AWS, no Azure, no Google Cloud.

EU-only sub-processors

Every component of our stack is provided by EU-based companies. Payment processing via Mollie (Netherlands), object storage via Scaleway (French company, data in nl-ams region, Netherlands), hosting and email processing via Hetzner (Germany).

No data transfers outside the EU

Email data never leaves EU jurisdiction at any point in the processing pipeline. This eliminates the need for Standard Contractual Clauses (SCCs), Transfer Impact Assessments (TIAs), or other Schrems II workarounds.

Data Residency Mode (Platform plan)

For organisations that need the strongest possible guarantees, Data Residency Mode ensures EmailConnect never persists email content in its database at all. Content flows through memory to your webhook and your own S3 storage — only routing metadata is retained by EmailConnect. This means there is no content to subpoena, no content to breach, and no content subject to any jurisdiction other than the one you choose for your S3 bucket.

Regulatory framework alignment
