The data-sovereignty differences.
EU server location is only one layer. The operator and transfer framework matter too.
Service-data location
- Postscale
- Primary production service data is hosted in the EU/EEA.
- MailerSend
- MailerSend says its service is hosted in Belgium through Google Cloud EMEA Ltd.
Transfer framework
- Postscale
- The EU operator documents subprocessors and safeguards for any limited transfers.
- MailerSend
- Its DPA names MailerSend, Inc. as data importer, an Irish GDPR representative, and contractual safeguards for third-country transfers.
CLOUD Act consideration
- Postscale
- The operator is an EU company. Disclosed subprocessors and transfer safeguards still belong in your review.
- MailerSend
- MailerSend's US operator can be subject to valid US legal process for data it controls, even when the service is hosted in Belgium.

Frequently asked questions
Does MailerSend host service data in the EU?+
Yes. MailerSend says its service is hosted in Belgium through Google Cloud EMEA Ltd. That is a genuine EU-hosting commitment and should not be confused with a US-only hosting model.
Who operates MailerSend?+
MailerSend's privacy policy identifies MailerSend, Inc., a New York company. Its DPA also names that company as the data importer and identifies MailerLite Limited in Ireland as its GDPR representative.
Why distinguish EU hosting from EU operation?+
Hosting describes where servers process or store data. Operator jurisdiction describes the company controlling the service and responding to legal process. A sovereignty review normally considers both, along with subprocessors and support access.
What does the CLOUD Act mean here?+
The CLOUD Act clarified that a covered US provider must comply with valid US legal process for data in its possession, custody, or control, even when stored abroad. It does not provide automatic government access, and EU hosting remains a useful control.
Does Postscale replace every MailerSend feature?+
No. Postscale focuses on transactional sending, inbound rules, masked addresses, authentication, and deliverability. MailerSend includes a broader template and collaboration surface, so compare those workflows separately.
How do I migrate from MailerSend?+
Verify a Postscale domain, replace the REST endpoint and token or SMTP credentials, import suppressions, map templates and webhooks, test inbound routes, and then shift production traffic gradually.
Move product email under an EU operator.
Open a Postscale account, verify a domain, and test your sending and inbound workflows.
