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 run history shows the failed step with its input and the error message Mailchimp returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Add List Member support batch operations?

Run Add List Member inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Mailchimp's rate limits.
