Typeform email verification with BillionVerify
Typeform is a popular form and survey builder known for its conversational, one-question-at-a-time interface. Integrating BillionVerify into your Typeform submissions means every email address collected from respondents is validated before reaching your CRM, email platform, or sales team.
Why verify before the send
Forms are a primary source of new contacts, but they also attract typos, fake entries, and disposable addresses from users who want to avoid follow-up. BillionVerify filters these out at submission time, so your marketing lists stay clean, your bounce rates stay low, and your email sender reputation stays intact.

How it works
- 1
A respondent submits a Typeform that includes an email field.
- 2
Typeform sends the response to an n8n workflow or Integrately automation via webhook.
- 3
BillionVerify verifies the address — checking format, domain MX records, SMTP reachability, disposable-service lists, and catch-all status.
- 4
A clear result is returned: valid, invalid, risky, or catch-all.
- 5
Your workflow forwards valid addresses to downstream tools and routes problematic ones to a review queue or triggers a notification.
When to use this
Clean lead generation forms in real time
Whenever a Typeform submission includes an email address, BillionVerify checks it immediately. Only verified addresses are forwarded to HubSpot, Salesforce, or your email platform — keeping your pipeline free of junk contacts.
Protect gated content and lead magnets
Users who enter a throwaway address to download a guide or access a demo are caught before your delivery automation runs. BillionVerify identifies disposable domains so your content stays valuable.
Maintain list hygiene across survey campaigns
Survey respondents sometimes enter inaccurate contact details. Verifying emails at the Typeform layer means your re-engagement or follow-up campaign starts with a clean, high-quality audience.
FAQ
How do I connect BillionVerify to Typeform?
Use Typeform's webhook feature to send submissions to n8n, where the BillionVerify community node handles verification. Alternatively, Integrately offers a 1-click setup between Typeform and BillionVerify.
Can BillionVerify detect typos in email addresses?
Yes. BillionVerify validates syntax and checks whether the domain actually exists and accepts mail, so a typo that produces an undeliverable address will be caught before it enters your list.
What should I do with addresses marked as catch-all?
Catch-all domains cannot be confirmed deliverable via SMTP alone. A common strategy is to accept them but tag them separately, then suppress them if they bounce on first send.
Does real-time verification work with Typeform's hidden fields or conditional logic?
Yes. BillionVerify operates at the webhook layer after submission, so it is independent of Typeform's internal logic — it works regardless of which fields or conditions your form uses.
