How do I subscribe a Klaviyo profile to a list?

Short answer: You can subscribe profile in Klaviyo by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Klaviyo Subscribe Profile action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

What inputs does Subscribe Profile require?
Required: List ID, Email. Every input accepts a static value or a variable from any upstream node in your workflow.
