How do I add a subscriber to a Mailchimp list?

Short answer: You can add list member in Mailchimp by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Mailchimp Add List Member action to a workflow, map its 5 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Add List Member.

What does the Add List Member action do in Mailchimp?
Adds a subscriber to a Mailchimp audience/list with email, status (subscribed/pending), merge fields, and tags. Use to push form fills or new customers into your email program.
What inputs does Add List Member require?
Required: Audience/List ID, Email Address, Status. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Mailchimp returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Add List Member support batch operations?
Yes. Run Add List Member inside a Loop node to process arrays. TinyCommand handles Mailchimp's rate limits automatically so you don't have to throttle manually.
