How do I look up a Mailchimp subscriber by email?

Short answer: You can get list member in Mailchimp by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Mailchimp Get List Member 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.
