Fastmail has been storing all customer email in the United States since it launched in 1999. That changed on August 3, 2026. The Australian email provider has opened its own data centre in Amsterdam and is now letting customers choose the European Union as the primary home for their data.
For European users who have been asking “but where does my email actually live?”, this is a meaningful answer. Whether it is the answer you were hoping for depends on exactly what you need.
What Fastmail has changed
The new infrastructure is based in Amsterdam and built by Fastmail’s own engineers. That detail matters: this is not a rented zone on AWS or Azure with a GDPR-friendly sticker on it. Fastmail owns and operates the hardware directly, the same way it has run its Philadelphia and St Louis data centres for over two decades.
The EU region is available now. If your Fastmail account is billed to an address in Europe, you have likely already been migrated automatically. Fastmail transferred an encrypted copy of those accounts to Amsterdam in advance of the announcement, and the primary copy will become your active data shortly. Your account kept working throughout the move.
If you were not automatically included, you can switch yourself: go to Settings → Users & Sharing → Team Settings, then look for the Data residency section under GDPR. The migration is queued and causes no disruption. You will see it progress from queued, to transferring, to done.
There is no extra charge for choosing the EU region. Fastmail considered a surcharge and decided against it.
What the EU region actually covers
When your account is set to the EU region, here is what changes:
- The primary, live copy of your mail and files sits on Fastmail’s own servers in Amsterdam
- Incoming mail routes to EU servers by preference, provided you are using your own domain with Fastmail’s nameservers, or an address on one of Fastmail’s designated EU-region domains
- The Fastmail web interface, desktop app, and mobile apps connect to Amsterdam infrastructure by default
- If the Amsterdam servers are ever unavailable, the apps fall back to US infrastructure automatically so you can still reach your inbox
For the vast majority of day-to-day use, your email flows through the EU. That is the practical change, and for many European users it is exactly what they wanted.
What still goes to the US
Here is where the picture gets more nuanced, and where Fastmail’s own transparency is worth paying attention to.
Because Fastmail currently has only one EU location, the geographically separate backup replica of your data is still stored in Philadelphia. That is standard practice: a resilient email service keeps copies in separate locations, and Amsterdam is the only EU option for now. A second EU site would change this, but none has been announced.
Emergency backups for all users, regardless of region, are also in Philadelphia. System logs are consolidated into a single US location for monitoring and customer support. Third-party services Fastmail uses for billing, debugging, and support are not specific to any region and apply to all accounts.
Fastmail says this plainly in the announcement: “If what you need is a guarantee that your data remains only in the EU, we don’t have that, and we’d rather tell you directly than let you assume otherwise.”
That kind of honesty is not common in this industry. It also means you should read the above carefully before deciding this solves a specific compliance requirement.
Why the Australian jurisdiction matters more than you might think
This is the part most coverage of this story has skipped.
A lot of the concern around data residency in Europe comes down to one question: can a foreign government compel your email provider to hand over your data? The US CLOUD Act is what makes European businesses nervous about using providers headquartered in the US, even ones with data centres in Frankfurt or Dublin. A US company operating EU servers is still subject to US law, and the CLOUD Act can reach data stored anywhere in the world by a US-incorporated entity.
Fastmail is not a US company. It is Australian, headquartered in Melbourne, and subject to Australian law and its own set of legal-cooperation treaties. That is a meaningfully different legal position. A US government subpoena does not automatically reach Fastmail the way it would reach Google or Microsoft.
That said, Fastmail is transparent that Australian law includes its own cooperation mechanisms with other governments, and that data location does not change how they respond to lawful authority requests from relevant jurisdictions. This is not a “no government can ever access your data” service. It is a more private alternative to US-based providers, with clearer data-handling commitments and no advertising model to fund.
If you need an email provider incorporated entirely within the EU, that is a different category. Providers like Infomaniak (Swiss, though not EU) operate under European legal frameworks by default. IONOS is another option worth considering if EU legal jurisdiction is the specific requirement. It is incorporated in Germany.
Who this is right for
For most European individuals and small businesses, this is a clear win. Your primary email data moves to the EU at no extra cost, with no disruption, and you get a clearer story to tell if anyone asks where your communications are stored. If you have been using Fastmail and feeling uncertain about the storage model that kept everything in the US, this resolves that concern for everyday purposes.
For businesses operating under GDPR who want to simplify their compliance documentation, having the primary data copy in the EU is a useful step. It does not automatically make you compliant, and it does not eliminate the need for a Data Processing Agreement, but it removes one friction point from the conversation with your legal team.
For organisations that need a hard contractual guarantee that email data never leaves EU borders, this is not quite there yet. The backup replica in Philadelphia and the US-based logs mean there are legitimate caveats to document. Fastmail’s own transparency report and data processing annex are worth reading before making that call.
The practical test: if your concern is “I want my email to live in Europe, with a provider I trust, at a price that makes sense,” Fastmail now passes that bar. If your concern is “I need to demonstrate to a regulator that zero bytes of this data ever leave the EU,” you will need to do more homework, or look at a different provider.
The bigger picture
This announcement sits inside a much larger shift happening across European tech. Businesses are increasingly asking not just “where is the data stored?” but “who has legal authority over the systems processing it?” Those are different questions, and the distinction between data residency and data sovereignty is becoming a live debate in compliance circles.
AWS launched a European Sovereign Cloud in Brandenburg, Germany, in January 2026, specifically to address the legal exposure gap that comes with using a provider headquartered in the US. Microsoft has its own EU Data Boundary programme. Fastmail’s move is smaller in scale but more direct: they own the hardware, they are not a US company, and they are not making promises they cannot keep.
The trend is clear. Data location is becoming a competitive differentiator, not just a compliance checkbox. The fact that Fastmail is doing this without a price premium says something about where the market is heading.
If you already use Fastmail and your account is billed to a European address, check your settings. You may already be on the EU region, or a few clicks away from it.
Frequently Asked Questions
Is Fastmail GDPR compliant?
Fastmail offers a Data Processing Agreement and gives European users the option to store their primary email data in Amsterdam. The EU data region simplifies GDPR compliance discussions, but it does not replace a proper review of Fastmail’s data processing terms for your specific use case. Backup replicas currently remain in the US.
Does Fastmail store data in Europe?
Yes, from August 2026 Fastmail stores the primary copy of data for EU-region accounts on its own servers in Amsterdam. Backup replicas and emergency backups are still stored in the US, and system logs are consolidated in a US location.
How do I switch my Fastmail account to the EU region?
Go to Settings → Users & Sharing → Team Settings, then find the Data residency section under GDPR. Select the EU region and Fastmail will queue and complete the migration. Your account stays accessible throughout.
Is Fastmail a European company?
No. Fastmail is an Australian company headquartered in Melbourne, founded in 1999. It is not subject to US law, which is a meaningful distinction compared to US-based providers, but it is also not incorporated in the EU. Australian law governs the company.
What is the difference between data residency and data sovereignty?
Data residency refers to where your data is physically stored. Data sovereignty refers to which government has legal authority to compel access to it. A US company with EU servers gives you EU residency but not EU sovereignty, because US law can still reach data held by a company incorporated in the US. Fastmail is an Australian company, which puts it in a different legal position, but backup data and logs still flow to the US.
