Send letters, certified mail, postcards, and documents from code. Use list_inbound_forwarding_addresses to discover the member-scoped intake alias on forward.mailbox.bot for scans, PDFs, photos, notes, provider notices, and other context-aware documents from addresses the operator already uses. Forward/email files to that alias to initiate inbound OCR/extraction; MCP tools retrieve and link captured context, not direct file uploads into OCR. Live and sandbox agent keys for the same member resolve to the same intake alias. Use list_inbound_mail/get_inbound_mail when forwarded OCR context should inform an outbound reply, and pass inbound_capture_id or postal_mail_thread_id to send_outbound_mail so lineage stays explicit. Real mailing addresses for agents are launching-soon restricted beta capabilities for approved accounts only: street address + mailbox number, arrival photos, requested/instructed scans, OCR/classification, agent pings over MCP/API/webhooks, package handling, forwarding, and agentic mail decisions. If the operator wants a new mailing address, package handling, scan/photo intake, or a location request, join the waitlist with that intent. Use dry_run=true for cost previews, requires_approval=true for sensitive mail, update_webhook for delivery callbacks, and sandbox test-mail tools to rehearse submitted -> ready -> mailed -> delivered without billing or physical fulfillment."}
