Surveysparrow email verification with BillionVerify
SurveySparrow is a conversational survey and feedback platform that makes it easy to collect responses via web, email, and chat. Integrating BillionVerify means every respondent email you collect is validated before it enters your CRM or triggers a follow-up sequence.
Why verify before the send
Survey respondents sometimes enter throwaway or mistyped email addresses, especially when an email field is required to submit. BillionVerify catches disposable, invalid, and role-based addresses at the point of collection so your follow-up emails reach real inboxes and your contact lists stay actionable.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Surveysparrow sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Surveysparrow
Ready-to-use workflows that verify emails before Surveysparrow sends.
How it works
- 1
Use SurveySparrow webhooks to send new response data to n8n or your integration layer the moment a survey is submitted.
- 2
Extract the email field from the webhook payload and pass it to BillionVerify via the n8n community node or REST API.
- 3
BillionVerify returns a deliverability status: valid, invalid, disposable, catch-all, or role-based.
- 4
Route the response: push valid emails into your CRM or email tool; tag or discard addresses flagged as invalid or disposable.
- 5
Optionally store the verification result alongside the SurveySparrow response for reporting and audit purposes.
When to use this
Validate respondent emails at submission
When a SurveySparrow response arrives containing an email field, automatically pass it through BillionVerify before routing the record to your CRM or email platform. Ensure only genuine addresses make it into your follow-up sequences.
Filter feedback contacts before outreach
After collecting NPS or CSAT responses, verify the associated email list with BillionVerify before sending follow-up communications. Reduce bounce rates and protect your sending reputation when closing the feedback loop.
Keep panel or audience lists clean
If you maintain a recurring survey panel in SurveySparrow, run periodic bulk verification against the member list to remove addresses that have gone invalid, reducing wasted sends and keeping panel metrics accurate.
FAQ
Can I verify emails in real time as surveys are submitted?
Yes. Combine SurveySparrow webhooks with the BillionVerify REST API or n8n node to verify each email immediately after submission, before it reaches your CRM.
What if a respondent enters a catch-all domain address?
BillionVerify flags catch-all addresses separately so you can decide how to handle them — some teams accept them with a lower confidence score, others suppress them from automated outreach.
Does this integration require technical knowledge to set up?
Using Integrately's 1-click setup requires no coding. For more custom logic — like conditional routing based on verification result — n8n offers a low-code visual builder.
Can I bulk-verify an existing SurveySparrow response list?
Yes. Export your response list, submit the emails to BillionVerify's bulk API, and re-import the results. You can automate this on a recurring schedule through n8n.
