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?

Does List Interest Groups support batch operations?
