Google Forms email verification with BillionVerify
Google Forms is one of the most common ways to collect email addresses from leads, event attendees, survey respondents, and newsletter subscribers. BillionVerify plugs into Google Forms workflows to verify each submitted email in real time, stopping invalid, disposable, and fake addresses from entering your list at the moment of collection.
Why verify before the send
Form submissions are a primary entry point for bad email data. People mistype addresses, use temporary inboxes, or submit fake emails to avoid follow-up. Every unverified submission that reaches your email tool raises your bounce rate and erodes your sender reputation. Catching these at the form stage — before they touch your CRM or list — is the most efficient place to filter them.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Google Forms sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

How it works
- 1
Connect Google Forms to BillionVerify using n8n's BillionVerify community node or via Integrately's 1-click setup.
- 2
A new form response triggers the verification workflow immediately after submission.
- 3
BillionVerify checks the submitted email for syntax validity, MX records, SMTP deliverability, disposable domain use, and catch-all status.
- 4
Based on the result, the contact is either added to your list and CRM, tagged with a status field, or silently excluded.
- 5
All verification results can be logged to a Google Sheet for auditing and reporting.
When to use this
Real-time validation on every form submission
The moment a Google Forms response arrives, trigger BillionVerify to check the email address. If it is invalid or disposable, the contact can be excluded from follow-up sequences automatically, ensuring only genuine subscribers are added.
Protect lead generation campaigns
Forms used for lead magnets and gated content attract a higher share of fake submissions. Verifying each email before passing it to your CRM or email platform means your sales team only works with contacts who provided a real, reachable address.
Event and webinar registration cleanup
Verify registrant emails collected through Google Forms before sending confirmation or reminder emails. This keeps your sending stats accurate and prevents wasted sends to addresses that will bounce.
FAQ
How quickly does verification happen after a form is submitted?
Verification is near-instant. The n8n or Integrately workflow triggers within seconds of a new response, and BillionVerify returns a result typically in under a second per address.
Will respondents know their email was rejected?
That depends on your workflow design. BillionVerify returns a status to your automation, but how you act on that — sending a notification, skipping the contact, or flagging them — is fully within your control.
Can I verify addresses from older Google Forms responses too?
Yes. You can export historical responses, run the email column through BillionVerify's bulk API, and import the results back to identify which past submissions have valid addresses.
Does BillionVerify catch role-based emails like info@ or contact@?
Yes. Role-based addresses are flagged as a separate category. These inboxes are typically monitored by teams rather than individuals and tend to have lower engagement, so you can choose to exclude them from automated follow-ups.
