Inbox Addresses and Domain Behavior

Each inbox has an address_token that forms a routable email address.

Address format

<address_token>@<inbound_domain>

The inbound domain is configured in your environment and must be connected to your email routing setup.

Operational guidance

Use stable tokens

Avoid recycling tokens between unrelated workflows to reduce confusion during replay/debug.

Separate environments

Use different tokens or domains for staging and production for safer rollout.

Label by use case

Name inboxes by workflow intent (for example invoices, alerts, support).

Common pitfalls

• Domain not configured in routing provider.
• Sending to a token that belongs to a different account.
• No active routing attached to an inbox receiving email.
