Field notes
The workflow separates drafting from dispatch: an assistant prepares the correspondence, then the sender reviews a proof PDF and confirms the exact charge before anything is mailed. The page names Meta Muse, Claude, and ChatGPT as connection points and exposes an MCP endpoint at /mcp. Pricing distinguishes ordinary First-Class mail, Certified Mail, electronic return receipts, faxes, and additional pages, with service limited to US addresses.
