robomotionio Resend
The robomotion resend CLI connects to Resend for transactional email delivery. It sends emails (HTML and text), manages contacts and audiences, handles domain verification, and supports batch email operations.
When to use
- Send transactional emails with HTML or plain text content
- Manage contacts and audience lists
- Verify and manage sending domains
- Send batch emails to multiple recipients
Prerequisites
robomotionCLI installed- Package installed:
robomotion install resend - Resend API key configured via Robomotion vault
IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls.
You MUST use --session on connect and pass --session-id to all subsequent commands.
Workflow
- Install (once):
robomotion install resend - Connect with session:
robomotion resend resend_connect --session --output json # → {"outClientId":"<client-id>","session_id":"<session-id>"} - Use the returned
client-idandsession-idin all subsequent commands:robomotion resend resend_send_email --client-id "<client-id>" --from <from> --to <to> --subject <subj> --html <body> --session-id "<session-id>" --output json - Disconnect when done:
robomotion resend resend_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
Always append --output json to get structured JSON results.
