What it does
You automatically move Zoom webinar registrants into your Mailchimp audience while filtering out internal emails and preventing duplicates. New contacts receive double opt-in confirmations to keep your list clean, and you can trigger this sync manually or on a schedule.

Watch out for
⚠ Zoom API has strict rate limits that can cause failures during large webinars, so implement a retry mechanism with exponential backoff in your code node.
⚠ Mailchimp double opt-in requires the user to click a link before they are active, so ensure your downstream workflows wait for the 'subscribed' status rather than just 'pending'.
⚠ Internal email filtering might accidentally block legitimate partners if you use overly broad domain matches, so verify your exclusion list includes only exact internal domains.
⚠ Webinar attendee lists can contain duplicate entries from multiple registration attempts, so add a deduplication step before sending data to Mailchimp to avoid API errors.
