Contracting operator
- Postscale
- DNScale OÜ, an Estonian company.
- Amazon SES
- AWS says EMEA customers generally contract with Amazon Web Services EMEA SARL in Luxembourg.
An Amazon SES alternative with a simpler EU boundary.
AWS gives EMEA customers a Luxembourg contracting entity and regional controls. Postscale narrows the review to one EU-operated product with EU/EEA-hosted primary service data.

The data-sovereignty differences.
AWS has strong regional controls. The practical difference is how much architecture sits inside the review boundary.
Service-data location
- Postscale
- Primary production service data is hosted in the EU/EEA by default.
- Amazon SES
- Customers choose an AWS Region. SES resources and endpoints are regional, with documented service-specific exceptions.
Architecture boundary
- Postscale
- Sending, inbound storage, rules, events, and logs sit inside one product boundary.
- Amazon SES
- A complete SES workflow can span S3, SNS, Lambda, EventBridge, CloudWatch, IAM, and their regional settings.
CLOUD Act consideration
- Postscale
- The operator is an EU company. Disclosed subprocessors and transfer safeguards still belong in your review.
- Amazon SES
- AWS has US operations and says the CLOUD Act can apply to providers with such operations. AWS also documents safeguards and that access is not automatic.

Frequently asked questions
Do EMEA customers contract with an EU AWS entity?+
Generally, yes. AWS says accounts in Europe, the Middle East, and Africa contract with Amazon Web Services EMEA SARL in Luxembourg, subject to the account and agreement details that apply to the customer.
Can Amazon SES keep resources in an EU Region?+
Yes. SES endpoints, identities, templates, suppression settings, and receiving capabilities are regional. A complete review must also cover each connected AWS service and any documented cross-region exception.
Why is Postscale's boundary simpler?+
Postscale includes sending, inbound parsing and storage, rules, signed webhooks, logs, and suppressions in one product. SES commonly composes several AWS services, so residency and access settings must remain aligned across the whole architecture.
What does AWS say about the CLOUD Act?+
AWS says the law does not give US authorities automatic access and that valid legal process is required. It also notes that the law can apply to cloud providers with US operations, not only companies headquartered in the United States, and describes its process for challenging requests.
When is Amazon SES the better fit?+
SES is a strong fit when deep AWS integration, granular infrastructure control, and ownership of the surrounding services are advantages for your team. Postscale is aimed at teams that want those email workflows inside one product.
How do I migrate from Amazon SES?+
Verify a Postscale domain, replace the SES API or SMTP credentials, map delivery events and receipt rules, move stored attachments and suppressions where required, test each path, and then shift traffic gradually.
Put product email inside one EU-operated boundary.
Open a Postscale account, verify a domain, and test your sending and inbound workflows.
