Mailgun (a Sinch company) offers an EU region where message data never leaves the region in which it is processed. You choose the region per domain at creation by using the EU API endpoint (api.eu.mailgun.net); the US endpoint is the default, and a domain’s region cannot be changed later. The residency is partial by design: account information, user accounts, billing details, API keys, and domain names are replicated globally, and the Sinch sub-processor list includes US group entities and US support tooling. The EU message stores run on Google Cloud data centers in Germany and Belgium. For teams (often German DPOs) that want the full data footprint in the EU, here are the best fully EU-hosted alternatives to Mailgun in 2026.

Common reasons

Why developers look for Mailgun EU alternatives

  • Partial EU residency: only message data stays in the EU region, while account information, user accounts, billing details, API keys, and domain names are replicated globally
  • Opt-in per domain: the EU region is chosen at domain creation via the EU endpoint, the US endpoint is the default, and the region cannot be changed later without deleting and recreating the domain
  • US sub-processors: the Sinch sub-processor list includes US group entities and US support tooling that can access data
  • US Cloud Act exposure: Sinch group entities in the US fall under the Cloud Act regardless of where message stores sit
  • Form-encoded API patterns and expensive pricing at scale compared with modern developer-first platforms
  • Enterprise and regulated teams (fintech, healthtech, public sector) often require the full data footprint, not just message data, to stay in the EU
Evaluation criteria

What to look for in an alternative

Key criteria to evaluate when choosing a Mailgun EU replacement.

  • No per-domain opt-in or endpoint choice that can silently route data through the US
  • GDPR compliance built in, with a published DPA and a clear sub-processor list
  • Low API latency from EU infrastructure for fast transactional email delivery
  • Type-safe SDKs with retry logic and idempotent requests
  • Deep-stack observability: API logs, email flow tracking, and webhook monitoring hosted in the EU
