Webinarjam email verification with BillionVerify
WebinarJam is a live webinar and virtual event platform built for marketers who need high-attendance broadcasts and interactive audience engagement. Adding BillionVerify to your registration workflow keeps your registrant list free of invalid, disposable, and catch-all addresses before your follow-ups go out.
Why verify before the send
A high-traffic webinar can accumulate thousands of registrations, and a meaningful share may come from fake or low-quality email addresses. When you send reminder emails or post-event follow-ups to a dirty list, bounce rates climb and your sender domain risks being penalized. BillionVerify intercepts invalid addresses at registration time so your deliverability stays intact for the emails that matter most.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Webinarjam sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

How it works
- 1
Set up a BillionVerify workflow triggered by new WebinarJam registrations using n8n or Integrately.
- 2
Each registrant's email is submitted to BillionVerify for a full verification check.
- 3
BillionVerify returns a status covering syntax validity, domain health, SMTP reachability, and disposable detection.

Registrants with invalid or risky addresses are flagged or removed before reminders are sent.
- 5
Your sending reputation stays protected as only real, reachable inboxes receive your event communications.
When to use this
Pre-Event List Scrubbing
Run registrants through BillionVerify before your reminder sequence begins. Catch invalid and disposable addresses early so your open and click rates reflect genuine attendee interest.
Filtering Bulk Registration Spam
Large webinar campaigns sometimes attract bot submissions. BillionVerify's disposable and syntax checks identify non-human registrations, letting you focus follow-up effort on real leads.
FAQ
At what point should I verify WebinarJam registrant emails?
Ideally at the moment of registration, so invalid addresses never enter your system. You can also run a batch verification on your list before sending pre-event reminder sequences.
Does BillionVerify check catch-all domains?
Yes. Catch-all domains accept any incoming address, making it impossible to confirm delivery. BillionVerify flags these so you can decide how to handle them in your follow-up strategy.
Can I use BillionVerify with WebinarJam without technical skills?
Yes. Integrately provides a 1-click integration that requires no code. For more complex workflows, the n8n community node offers visual automation with flexible branching logic.
