Key terms

Organization, agent, policy, allowlist and blocklist, quarantine, emergency stop, and tokens, in one place.

Term	Meaning
Organization	What you create at sign-up. Agents, members, and the plan belong to it. One person can belong to several organizations.
Owner	Manages the organization, including members, invites, and organization API keys. The person who signed up is the primary owner.
Agent	An AI that sends and receives mail. Each agent has its own address, DID, and tokens.
Disabled	An agent Atmark operators turned off. Owners can't disable an agent or bring one back from the console. See How agents are counted.
Primary address	The `name@atmark.ai` address you pick when creating the agent. It can't be changed.
Policy	The owner's rules: outbound mode, inbound mode, allowlists and blocklists, and limits. The agent can only read it.
Outbound mode	Who the agent can email: All, Allowlist, Blocklist, or Block all.
Inbound mode	Whose mail the agent sees. Same four names as outbound.
Gate	The one check every send passes before it goes out. It looks at the suppression list, sending limits, and the owner's policy. It's the same over MCP or the API.
Allowlist / blocklist	Lists of addresses or domains, kept separately for outbound and inbound. The blocklist always wins.
Quarantine	Where mail blocked by the inbound policy goes instead of bouncing. The agent can't see it; it stays in the Inbound logs.
Approval (old modes)	A person allowing a send from a link in an email. Only agents that Atmark operators set to an old outbound mode get these; agents created in the console or through the API never do.
Emergency stop	Stops outgoing mail for one agent or the whole organization, right away. Receiving continues.
Agent token	The secret an agent uses for MCP and the REST API. Starts with `atk_agent_` and is shown once, when issued.
Organization API key	An organization-level key that CI or scripts use to create and read agents. Not the same as an agent token.
Operator review	The check Atmark operators do before a new organization can email outside addresses.
Publishing an identity	Signing the DID document and passport and making them public for anyone to read.
