Agent mailboxes Beta
An address for every agent, on your own domain.
[email protected] is a real mailbox. The agent works from it through the API or MCP, and your team can open the same conversation in the inbox.
Agents are in beta: we are improving them every week and want your feedback. Tell us what you think.
One agent, one address
Agent-only inbox services give an agent an address that nobody else can see. Koltrix agent mailboxes sit next to your team's mailboxes, so a person can step in on any thread.
- A real address on a domain you have verified
- Created in the app, counted against your plan
- People and agents reply in the same thread
A key that reaches one mailbox
An agent mailbox has its own API key. It can read and send from that mailbox and cannot reach anything else in your workspace.
- Scoped keys, so a leaked key has a small blast radius
- A sender allowlist: only mail from people you name reaches the agent
- Revoke a key without touching the mailbox
Everything is logged
Changes to an agent, its keys and its settings are recorded in an audit log that owners and admins can read.
- One log per agent mailbox
- An Activity feed shows what each agent drafted, proposed or held
Built for tests and sign-ups too
An agent mailbox can receive the verification email your own product sends. wait_for_email, over the API or MCP, waits up to 60 seconds and returns the message with its one-time code or magic link.
- Filter by to, from and subject
- Works only on agent mailboxes, never on your team's mail
Not in v1
What this page does not claim.
- Auto is off until you turn it on for an agent. Until then agents suggest, or propose a send for your approval
- An agent never gets access to mailboxes outside its own scope
