Zoom email verification with BillionVerify
Zoom is a widely used video communications platform for meetings, webinars, and virtual events. By integrating BillionVerify, you can verify registrant email addresses before webinar confirmations are sent, keeping your attendee lists accurate and your sending reputation intact.
Why verify before the send
Webinar and meeting registration forms are frequent targets for fake or disposable email signups that inflate headcount numbers and waste confirmation sends. Invalid addresses cause bounces, hurting the domain used to deliver joining links and reminders. BillionVerify validates registrant emails at the point of signup so only reachable participants receive communications.

When to use this
Screen webinar registrants in real time
Connect Zoom's webinar registration event to BillionVerify so every new signup is checked before the confirmation email is dispatched. Registrants using disposable or invalid addresses can be declined or flagged for manual review, protecting your attendee data quality.
Protect reminder and follow-up email campaigns
Post-webinar follow-ups, recording links, and survey invitations all depend on valid addresses. Running your registrant list through BillionVerify before those sends reduces bounce rates and keeps your domain reputation healthy for future events.
Audit registration lists before large events
Before a high-stakes product launch or conference, bulk-verify the full registrant list using BillionVerify's REST API. Identify and suppress unreachable or suspicious addresses before investing in event-day communications.
FAQ
Can I automatically decline Zoom registrations from disposable email addresses?
Yes. Using n8n or Integrately, you can build a conditional workflow that calls Zoom's registration approval API to decline or pend registrants whose addresses BillionVerify flags as disposable or invalid.
Does this work for both meetings and webinars?
It works best with Zoom Webinars, which have formal registration flows. For standard meetings with registration enabled, the same integration pattern applies via Zoom's API and webhooks.
Will legitimate registrants experience any delay?
BillionVerify's API responds in well under a second, and the verification step can run asynchronously after the user submits the form, so the perceived experience for real registrants is seamless.
What about catch-all email addresses from corporate domains?
Corporate catch-all addresses are common and may belong to genuine attendees. BillionVerify returns a distinct catch-all status so you can choose to allow them while still blocking clearly invalid or disposable addresses.
