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. How it works Manual Trigger – Execute workflow** The workflow starts manually. You can optionally replace the manual trigger with a Schedule Trigger if you want to automate recurring webinars. Manual Input – Set Webinar ID and Occurrence ID** The workflow includes a Set node that requires you to enter: webinar_id occurence_id These define which Zoom webinar instance will be synced. Zoom API – Get Webinar Attendees** Retrieves registrants for the selected webinar occurrence using the Zoom API. Code Node – Extract Registrant Emails** Processes the Zoom API response and extracts the email addresses of all registrants. Filter Node – Filter Out Internal Emails** Removes internal/company email addresses by checking that they do not contain your domain. (This is fully configurable.) Mailchimp – Update a Member** Attempts to update the contact in Mailchimp based on their email address. This determines whether the contact already exists. IF Node – If ID Doesn’t Exist** Checks if Mailchimp returned an id during the update attempt. If Mailchimp did not return an ID, the contact is treated as new and continues through the creation + confirmation path. Code Node – MD5 Hash Email** Hashes the email using MD5. Mailchimp uses this hash as the unique identifier for list members. Mailchimp – Send Double Opt-In Email** Creates the contact with “pending” status and sends a double opt-in email. Mailchimp – Add Leads Tag** Tags the contact with "Leads" immediately as part of the creation process.
