FAQ

Questions about List Interest Groups.

What does the List Interest Groups action do in Mailchimp?

Lists interest categories (groups) in a Mailchimp audience. Use to power a preference-center UI or to segment a blast by interest.

What inputs does List Interest Groups require?

Required: List ID. 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 List Interest Groups support batch operations?

Yes. Run List Interest Groups inside a Loop node to process arrays. Tiny Command handles Mailchimp's rate limits automatically so you don't have to throttle manually.
