resend-cli

Before running any resend commands, check whether the CLI is installed: If the command is not found, install it using one of the methods below: cURL (macOS / Linux): Homebrew (macOS / Linux): Node.js: PowerShell (Windows): After installing, verify: The CLI auto-detects non-TTY environments and outputs JSON — no --json flag needed. Rules for agents: Auth resolves: --api-key flag > RESEND_API_KEY env > config file ( resend login --key ). Use --profile or RESEND_PROFILE for multi-profile. Read the matching reference file for detailed flags and output shapes. Dry-run: Only emails send and broadcasts create support --dry-run (payload validation before send/create). They print { "dryRun": true, "request": { ... } } on stdout without calling the API. There is no --dry-run on emails batch , broadcasts send , or other commands yet. Send an email: Send a React Email template (.tsx): Domain setup flow: Create and send a broadcast: CI/CD (no login needed): Check environment health: - Supply ALL required flags.
