Vendor profile
Postmark: where is customer data stored and processed?
Postmark, owned by ActiveCampaign, LLC in the USA, stores customer data in the USA, specifically Chicago. Primary data and servers are hosted at Deft outside Chicago and at AWS, but the AWS region is not stated. Processing runs on the same servers and infrastructure as storage. The customer group is not stated, and no certifications are listed. The data processing agreement has been read, but it does not state where data is stored, so the storage location comes from other sources. Support, notifications, identity, backup, telemetry and usage analytics are all listed without a stated location. Zendesk, a US-based helpdesk tool, is named as a sub-processor for customer communication.
