Sync Zoom webinar attendees to Mailchimp with double opt-in and email filtering

Description

Use this workflow to automatically sync Zoom webinar registrants into Mailchimp, filter out internal contacts, and send double opt-in confirmation emails. Ideal for keeping your newsletter audiences clean, accurate, and enriched with new leads—without manual export/import steps.

About Workflow

This workflow connects Zoom Webinars with Mailchimp via API to automate the onboarding of webinar attendees into your marketing audience. It retrieves registrant data from Zoom (based on Webinar ID and Occurrence ID), extracts attendee emails, filters out internal domains, checks whether the contact already exists in Mailchimp, and then creates or updates each record. New contacts receive a double opt-in confirmation email, and all newly added leads are tagged for segmentation inside Mailchimp.

Use Case

Perfect for marketing teams running webinars who need to transfer participants into Mailchimp quickly and reliably. This automation streamlines attendee follow-up, ensures compliance with double opt-in requirements.
