Data Regions
PostStack is hosted in the European Union with full data residency. All customer data — outbound emails, contacts, templates, attachments, audit logs, webhook deliveries — lives exclusively on EU infrastructure and is never replicated outside the region.

Why EU only?
PostStack is operated from Denmark by a European company. Running entirely in the EU means a single, unambiguous answer to data residency, GDPR, and cross-border transfer questions: there are no transfers. We'd rather be excellent in one jurisdiction than mediocre across two.
Discovering regions programmatically
