Pop is a terminal-based email client that brings email sending directly to your command line. Whether you prefer an interactive text-based interface or scriptable CLI commands, pop adapts to your workflow.

Key capabilities include:

Dual interface modes: Launch an intuitive full-screen compose interface or use command-line flags for quick sends
Multiple delivery methods: Send through SMTP servers or Resend API with simple environment variable configuration
Content flexibility: Write emails in Markdown, read from stdin or files, and preview before sending
Attachments: Easily attach files directly from the command line
Automation-ready: Perfect for scripts, CI/CD pipelines, and AI agent integrations without custom code
Preset configuration: Store sender details and signatures in environment variables to avoid repetitive typing

Pop is ideal for developers who want to test email functionality locally, integrate email sending into automated workflows, or simply prefer managing correspondence from the terminal. It integrates seamlessly with other CLI tools like mods for AI-generated content, gum for interactive selections, and invoice generators for complete email pipelines.
