FAQ

Questions about Update List Member.

What does the Update List Member action do in Mailchimp?

Updates an existing Mailchimp list member's status, merge fields, tags, or interests. Also the right call for setting status="unsubscribed" without deleting.

What inputs does Update List Member require?

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 Update List Member support batch operations?

Run Update 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.
