FAQ

Questions about Create Tag.

What does the Create Tag action do in Mailchimp?

Creates a new tag (static segment) in a Mailchimp audience. Tags are how you scope blasts to a cohort without a saved segment query.

What inputs does Create Tag require?

Required: List ID, Tag Name. 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 Create Tag support batch operations?

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