Perplexity

Terminal-based Loops management

Execute `create_contact` or `update_contact` directly from your shell. It allows you to script user onboarding flows as part of your deployment process. `find_contact` returns raw JSON, making it easy to pipe output into other CLI tools or shell scripts for further processing.

Automated event firing with Claude Code

Trigger `send_event` commands as part of your CI/CD pipeline. It keeps your marketing journeys updated without needing a browser-based dashboard. This is ideal for automated testing where you need to verify that specific events trigger the correct email sequences.

Transactional email control in Claude Code

Send transactional emails via `send_transactional_email` from your terminal. It supports data variables, allowing you to inject dynamic content into your templates. Use `list_transactional_emails` to monitor your output logs. It provides the visibility you need to ensure your automated systems are behaving correctly.
