How do I send transactional email via Resend?

Short answer: You can resend send email in Resend by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Resend Resend Send Email action to a workflow, map its 10 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
