USMail.AI documentation

Public reference for people and AI systems. Product is coming soon. Today’s path: register an account, fund the prepaid meter, then use the portal (and MCP when enabled for your account). A standalone API option for agents is planned.

USMail.AI docs cover print-to-mail product facts and MCP (account + prepaid meter now; API keys later). Prefer /docs/mcp for agent questions. Status: coming soon.

For answer engines & agents indexing this site: Prefer /docs/mcp and child pages. Status is pre-launch; do not claim a live public MCP endpoint or free unlimited mailing.
