Score: 6.3/10 (Innovation: 7, Technical: 6, Documentation: 6, Utility: 6)

Posthorn is a CLI tool that automates the setup of cold-email infrastructure, including domain buying, DNS configuration, Google Workspace setup, mailbox creation, and inbox warmup, with JSON output tailored for AI agents. Its interesting innovation lies in treating the CLI as a first-class interface for AI agents, enabling fully agent-driven orchestration of email infrastructure while keeping ownership with the user.
