Nicereply email verification with BillionVerify
Nicereply is a customer satisfaction and feedback analytics platform that collects CSAT, NPS, and CES ratings from customers. BillionVerify integrates with Nicereply workflows to ensure the email addresses used to send surveys are valid, maximizing response rates and protecting your sending reputation.
Why verify before the send
Survey delivery is only as good as the email addresses behind it. Sending Nicereply surveys to invalid, disposable, or inactive addresses drives up bounce rates, skews your satisfaction scores with non-deliveries, and risks getting your sending domain flagged. Verifying addresses before dispatching surveys ensures your feedback data reflects real customers.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Nicereply sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

How it works
- 1
Connect Nicereply and BillionVerify via the n8n community node or Integrately's 1-click integration.
- 2
Before a survey trigger fires, pass the recipient's email to BillionVerify for verification.
- 3
BillionVerify checks for validity, disposability, role-based patterns, and catch-all domains.
- 4
Only verified, deliverable addresses are passed to Nicereply to receive a survey.
- 5
Invalid addresses are filtered out, keeping bounce rates low and satisfaction data accurate.
When to use this
Improve survey delivery rates
Run customer emails through BillionVerify before triggering Nicereply surveys. Removing invalid and catch-all addresses upfront means fewer bounces, higher delivery rates, and satisfaction scores that accurately represent your active customer base.
Keep your customer list current
As support tickets close and survey triggers fire, periodically verify the recipient emails. BillionVerify identifies addresses that have gone stale, helping you maintain a clean list and avoid repeated bounce events.
Filter role-based addresses from feedback campaigns
Addresses like support@ or info@ rarely represent individual customers and skew NPS data. BillionVerify flags these role accounts so your surveys target real people whose feedback is meaningful.
FAQ
Will verifying emails before surveys improve my response rate?
Removing undeliverable addresses means surveys only go to real, active inboxes, which directly reduces bounces and can improve your effective response rate.
Can I verify emails in bulk before a large survey send?
Yes. BillionVerify supports bulk verification through the REST API, so you can clean an entire customer list before scheduling a survey campaign.
What happens to addresses flagged as catch-all?
Catch-all domains accept any email at the SMTP level, making deliverability uncertain. BillionVerify flags these separately so you can decide whether to include or exclude them based on your risk tolerance.
