We built the CLI for scripts and AI agents as much as for people:
- JSON output, so you can pipe it straight into jq
- A separate exit code for each kind of failure (bad credentials, rejected request, worth retrying), so scripts know what went wrong
- --dry-run on every command prints the exact request without sending it
- Reads your API key from a credentials file, so agents never need it on the command line
Install it with Homebrew:
brew install helo-email/tap/helo
Or with one line:
curl -fsSL https://raw.githubusercontent.com/helo-email/helo-cli/main/install.sh | sh
There are builds for macOS, Linux and Windows. Docs: https://docs.helohq.com/getting-started/cli
