In 2026, most AI tools that promise to triage or draft your professional emails process that content on servers located outside the European Union. For an agency, a firm, or an SME exchanging emails with European clients, prospects, or candidates, that means personal data flows through infrastructure governed by a different legal regime than GDPR, often without the company ever checking before subscribing. Here is why that detail matters, and how to verify it before adopting an AI assistant for your inbox.
Why choosing an AI email assistant carries a GDPR risk
An AI assistant that reads or drafts your emails necessarily has access to the content of your conversations: prospect contact details, client files, HR exchanges, contractual information. If that processing happens on servers located in the United States or in a country without an adequacy decision, the company has to rely on specific safeguards (Standard Contractual Clauses, the Data Privacy Framework) whose legal validity has already been challenged more than once since the invalidation of Privacy Shield.
Beyond the legal risk, it is a practical problem: every additional non-EU subprocessor adds a line to your records of processing activities, a contract to sign, a transfer impact assessment to document. And a growing number of enterprise clients now reject, in their vendor security questionnaires, any tool that adds AI processing outside the European Union, regardless of the contractual safeguards in place.
How to assess and reduce this risk before adopting an AI tool
Map where the data is actually processed, not just where the vendor is headquartered
A company headquartered in France can still send the content of your emails to a model hosted in the United States for inference. The vendor’s registered office says nothing about where the processing actually happens. The only way to know is to read the tool’s technical documentation or its DPA (Data Processing Agreement), which should list, clause by clause, every subprocessor and its hosting country. If that document does not exist or stays vague (“secure cloud infrastructure”), that is already a warning sign: a vendor that genuinely processes data in Europe leads with that fact, it does not bury it.
Require processing with no content retention
The second risk, separate from location, is retention. A tool that stores email content to “improve the service” or train its models multiplies the exposure in case of a data breach, and complicates the right to erasure for the people concerned. Stateless processing, where the email content is analysed and immediately discarded without being logged or reused, mechanically reduces the risk surface, even when part of the technical infrastructure remains outside the EU (which is the case, for instance, for read access to the Gmail or Outlook APIs themselves, hosted by Google and Microsoft).
Check hosting, certifications, and human control before signing
Before activating an AI assistant on a professional mailbox, three checks usually suffice: the hosting country of the infrastructure (not just the vendor’s registered office), the existence of recognised certifications (ISO 27001, CASA for Gmail integrations), and how sending works. A tool that sends emails automatically without human review puts the company’s liability on every message, a risk that extends well beyond GDPR alone.
How Scribarius meets this requirement natively
Scribarius was built for European companies that cannot afford to add a non-EU subprocessor to their records of processing activities. The infrastructure is hosted exclusively in France (OVH Cloud, Scaleway), and the semantic analysis engine runs on Mistral AI, whose servers are located within the European Union. No data is transferred outside the EU by Scribarius.
Email content is never stored or used to train a model: it is processed in real time and immediately discarded, a stateless architecture documented in our DPA, compliant with Article 28 of the GDPR. Smart Templates and Smart Labels work on the same principle, and no email is ever sent without explicit validation: every suggestion stays a draft until a team member has reviewed it.
The full detail of these safeguards, hosting, encryption, certifications, is available on our security page.
Verify before you adopt, not after an incident
Choosing an AI assistant for professional email is no longer just a product decision, it is a compliance decision. Checking where the data is processed, whether it is retained, and who keeps final control over sending takes a few minutes and avoids months of remediation later.
