โ All Forms
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.
Ready-to-use n8n workflow
Import this workflow into n8n โ it verifies every address with BillionVerify before Typeform sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

Ensure your sheet has columns for \"Name\", \"Email\", \"Phone\", \"Registration Date\", \"Event Name\", \"Event Date\", \"Payment Status\", \"Follow-up Sent\", and \"Follow-up Date\".\n * You will need to set up Google Sheets OAuth2 API credentials.\n4. **Stripe (Process Payment):** Replace `<__PLACEHOLDER_VALUE__Customer ID__>` and `<__PLACEHOLDER_VALUE__Source ID__>` with your Stripe customer and source IDs. You will need Stripe API credentials.\n5. **Gmail (Send Confirmation Email, Send Reminder Email, Send Thank You & Survey):** You will need to set up Gmail OAuth2 credentials.\n6. **Google Calendar (Add to Calendar):** You will need to set up Google Calendar OAuth2 API credentials.\n7. **Slack (Notify Organizer):** Replace `<__PLACEHOLDER_VALUE__Slack Channel ID__>` (if not already set in Workflow Configuration) and set up Slack OAuth2 API credentials.\n8. **Survey URL (Send Thank You & Survey):** Replace `<__PLACEHOLDER_VALUE__Survey URL__>` with the link to your post-event survey.\n\n### Requirements\n\n* Typeform account and a registration form.\n* Google Sheet for participant management.\n* Stripe account for payment processing.\n* Gmail account for sending emails.\n* Google Calendar for event scheduling.\n* Slack account for organizer notifications.\n* n8n credentials for Google Sheets, Stripe, Gmail, Google Calendar, and Slack.\n\n### How to customize the workflow\n\n* **Reminder/Follow-up Timing:** Adjust the `reminderDaysBefore` and `followupDaysAfter` values in the \"Workflow Configuration\" node to change when reminder and follow-up emails are sent.\n* **Email Content:** Modify the HTML content in the \"Send Confirmation Email\", \"Send Reminder Email\", and \"Send Thank You & Survey\" nodes to match your branding and messaging.\n* **Payment Currency:** Change the `currency` in the \"Process Payment\" node if your event uses a different currency.\n* **Additional Data:** Extend the Google Sheets nodes to capture more participant information from Typeform if needed.\n* **Integration:** Easily integrate with other services by adding more nodes, for example, a CRM to add new participants as leads.\n`"

}Workflow templates with Typeform
Ready-to-use workflows that verify emails before Typeform sends.
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 โ 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 โ 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 โ it works regardless of which fields or conditions your form uses.
