How do I trigger when a new Mailchimp subscriber is added?

Short answer: In TinyCommand, add the Mailchimp New Subscriber trigger to a workflow and publish. It listens through a Mailchimp webhook and fires your workflow within seconds of the event, with no polling and no code. Add a filter if you only want some events to start a run.

FAQ

Questions about New Subscriber.

How does the New Subscriber trigger work in Mailchimp?

Fires when a new subscriber is added to a Mailchimp audience. Common use: sync to CRM, fire a welcome flow elsewhere, or notify Slack on lead-gen subscribes.

Is the New Subscriber trigger real-time?

Yes. New Subscriber uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Mailchimp.

What data does New Subscriber return?

The full event payload from Mailchimp. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.

Can I filter New Subscriber so only some events start a workflow?

Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.

Do I need Mailchimp admin permissions to use New Subscriber?

For most Mailchimp accounts a standard user can authorize the trigger. Some Mailchimp plans require an admin to enable third-party webhooks. Check Mailchimp's docs if the trigger fails to register.
