Demio email verification with BillionVerify
Demio is a webinar and virtual event platform designed for marketers who need professional, branded live and automated sessions. BillionVerify helps ensure that every registrant email is real and deliverable, so your webinar confirmation and reminder emails actually reach attendees.
Why verify before the send
Webinar registrations are only as valuable as the emails behind them. Invalid or disposable addresses lead to bounced confirmations, missed reminders, and inflated registration numbers that misrepresent actual attendance. BillionVerify validates registrant emails so your event metrics and delivery rates remain accurate.
Ready-to-use n8n workflow

How it works
- 1
Connect BillionVerify using the n8n community node, Integrately, or the REST API.
- 2
Trigger a verification check when a new webinar registration is submitted.
- 3
BillionVerify checks the address for validity, disposable domains, catch-all status, and role accounts.
- 4
Valid registrants proceed to receive confirmation and reminder emails; invalid ones are flagged or blocked.
- 5
Review verification results to gain insight into the quality of traffic arriving at your registration pages.
When to use this
Validate registrant emails at webinar sign-up
When someone registers for a Demio event, check their email with BillionVerify before confirming. Catch disposable and invalid addresses at the door so confirmation and reminder sends are not wasted on unreachable inboxes.
Protect automated follow-up sequences
After a webinar, automated replay and follow-up emails go to everyone who registered. Verify emails upfront to ensure these sequences only reach real attendees, keeping your marketing automation costs and bounce rates low.
FAQ
Why do disposable email addresses cause problems for webinar platforms?
Disposable inboxes are deleted shortly after use, so confirmation and reminder emails bounce. This inflates your bounce rate, skews attendance metrics, and wastes your email send allowance.
How do I connect BillionVerify to Demio?
Use the BillionVerify REST API in a webhook triggered by new Demio registrations, or set up the connection through n8n or Integrately for a no-code approach.
Can BillionVerify verify emails fast enough for real-time registration flows?
Yes. Single-address verification through the BillionVerify API typically completes in under a second, so registrants experience no noticeable delay at sign-up.
Does verifying emails help with webinar attendance rates?
Indirectly, yes. When confirmation and reminder emails reliably reach valid inboxes, more registrants actually show up. Filtering bad emails also gives you a more accurate picture of genuine registration intent.
