Every project is bound
to one region.

Choose a region when you create a project. Boundry keeps message processing, queues, logs, suppression lists, and operational storage in that region.

Sydney is live:
region 01.

A project is permanently bound to one region. Sydney (ap-southeast-2) is live today; its Laravel API, message processing, logs, suppression lists, and operational storage stay there.

Cloudflare manages the account control plane; it never proxies message content. Once a message is delivered, the recipient’s mailbox provider is outside Boundry’s control.
