All Infrastructure in Finland
EuroMail runs its entire infrastructure in Hetzner's Helsinki data center (hel1 region), located in Finland. Every component of the stack (API servers, background workers, SMTP engines, PostgreSQL databases, Redis queues, and object storage) operates within Finnish borders. There are no edge nodes, CDN pop-ups, or replicas outside the European Union.
This means that from the moment your application calls the EuroMail API to the moment an email leaves our SMTP engine, your data never crosses an EU border.
No Delivery Relay Outside the EU
EuroMail does not rely on any third-party service for email delivery. Unlike providers built on top of Amazon SES, SendGrid, or Mailgun, EuroMail delivers email directly from its own SMTP engine to recipient mail servers, so your email content never passes through a non-EU delivery relay.
A small, named list of ancillary subprocessors is still involved outside the delivery path: payment processing and source-code hosting (neither receives email content), abuse protection on account registration, and a US-based large language model that our pre-send scam classifier falls back to — with the subject line and up to 4,000 characters of the body — when the self-hosted classifier is unavailable. The full list, purpose, data shared and location of each is in the DPA.
The Data Lifecycle
Every stage of EuroMail's data lifecycle stays within Finland:
- API ingestion. Your application sends email data to our API endpoints hosted in hel1.
- Queue processing. Email jobs are queued in Redis and picked up by worker processes, all running in hel1.
- SMTP delivery. Our Rust SMTP engine connects directly to recipient MX servers from Finnish IP addresses.
- Storage. Email metadata, delivery logs, templates, and analytics are stored in PostgreSQL databases in hel1.
Data Processing Agreement
A Data Processing Agreement (DPA) is included with all EuroMail plans, including the free tier. The DPA covers all GDPR Article 28 requirements and clearly specifies Finland as the sole processing location. You can download the DPA from the legal section at any time.
Schrems II Considerations
Because EuroMail's core infrastructure — API, workers, SMTP engine, databases, and object storage — processes email content and account data exclusively within the EU, there is no transfer of that data to analyze under the Schrems II ruling of the Court of Justice of the European Union. The ancillary subprocessors named above and in the DPA are covered by EU Standard Contractual Clauses (SCCs).
Simplified Vendor Assessments
For B2B customers, EuroMail's architecture significantly simplifies vendor assessments and procurement reviews. When your legal or compliance team evaluates email providers, they can confirm that email content and account data stay within the EU, and review a short, named subprocessor list in the DPA rather than an open-ended sub-processor chain.
