How our MCP will allow AI agents to order

  1. Someone asks their LLM
    "Mail a welcome-back offer to customers who haven't ordered in 90 days."
  2. The agent builds the order
    List and design done directly via their LLM, only coming to our site to confirm and pay.
  3. We clean the list
    Address verification, CASS and NCOA run on every order.
  4. We print and mail
    As soon as the next business day.
