FAQ

Built around one simple idea.

Is InboxTron another email client?

No. InboxTron provides programmable email identities for agents and applications. A human UI is available for inspection, but MCP and REST are the primary automation interfaces.

Can I use my own domain?

Yes. Paid accounts can connect and verify a custom domain, then create agent addresses on it.

Do I need MCP?

No. MCP-compatible agents can use the MCP endpoint, while any application can use the REST API.

Can I start without configuring DNS?

Yes. Hosted InboxTron addresses are designed to get an agent receiving email quickly.
