Data sovereignty

Compliance review: Lettermint vs Mailjet

Mailjet is a European company too, hosted in Google Cloud regions in the EU. But Google is a US hyperscaler under the CLOUD Act, and Mailjet is part of the Sinch group. Digital sovereignty in practice looks different: Lettermint runs its own infrastructure in the EU and publishes its DPA, subprocessor list and ISO 27001 certification. You can check every claim document by document. Below are the facts your privacy or legal team will ask for.

EU data residency

Email data is hosted, stored and processed in the EU on sovereign infrastructure Lettermint owns and operates, as a written commitment in the DPA.

About our EU infrastructure

Data Processing Agreement

Lettermint is your processor under Article 28 GDPR. The public DPA covers security and audit rights and is countersigned on request.

Read the Data Processing Agreement

Subprocessors

Every subprocessor is listed publicly, with what it does and where it processes data. Changes are announced 30 days ahead.

View the subprocessor list

Your data stays yours

Email data is never used for model training, fine-tuning or research, and is processed only on your documented instructions.

Data use terms in the DPA

No longer than needed

We keep your data only as long as your account needs it. Close your account and everything is deleted, exactly as the DPA sets out.

Deletion terms in the DPA

International transfers

No transfers outside the EEA on Lettermint's initiative. Email to recipients outside the EU is delivered only at your instruction.

How EU-only delivery works

Certification

ISO/IEC 27001:2022 certified. Our security controls are continuously monitored, with live status, policies and certificates in the Trust Center.

Our ISO 27001 certification

EU jurisdiction, outside the CLOUD Act

Lettermint B.V. is incorporated in the Netherlands under EU law, with no US parent company, so the US CLOUD Act does not reach your email data.
