CINC email verification with BillionVerify
CINC is a real estate CRM platform designed to help agents and brokers capture, nurture, and convert leads. Integrating BillionVerify into your CINC workflows ensures the email addresses on leads and contacts are valid before you invest time and marketing spend in nurturing them.
Why verify before the send
Real estate leads often come from high-volume advertising campaigns where form quality varies widely. Disposable emails, typos, and fake submissions inflate your CRM contact count and drain drip campaign budgets. BillionVerify identifies invalid and throw-away addresses at entry so your agents focus only on genuine prospects.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before CINC sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with CINC
Ready-to-use workflows that verify emails before CINC sends.
How it works
- 1
Connect CINC to n8n or use Integrately to trigger a workflow whenever a new lead is added.
- 2
Extract the lead's email address from the CINC record.
- 3
Send the address to BillionVerify for verification via the n8n node, Integrately action, or REST API.
- 4
Receive a verdict — valid, invalid, disposable, role, or catch-all — within milliseconds.
- 5
Update the CINC lead record with the verification status or suppress invalid contacts from campaigns.
When to use this
Screen leads at the point of capture
Verify every inbound lead email the moment it arrives in CINC. BillionVerify flags disposable, invalid, and role-based addresses before they enter your nurture sequences, keeping your pipeline quality high.
Reduce email bounce rates on drip campaigns
Before launching a drip campaign from CINC, run your segment through BillionVerify to remove addresses that would bounce. Lower bounce rates protect your sender score and improve deliverability to genuine prospects.
Audit and clean your existing CINC contact database
Use the BillionVerify bulk API to validate your entire CINC contact list periodically. Remove or suppress invalid addresses to keep your database lean and your reporting accurate.
FAQ
How quickly does BillionVerify verify an email from CINC?
Most verifications complete in under a second, so the check can run silently in the background immediately after a lead is captured without delaying any user-facing confirmation.
Will verifying lead emails affect my CINC lead count?
BillionVerify only validates; it does not delete records. You control whether to suppress or remove flagged contacts based on the verification result returned to your workflow.
Can I verify leads coming from third-party portals that feed into CINC?
Yes. If those leads flow into CINC via webhook or API, you can intercept them in n8n or Integrately, verify the email, and then pass only clean leads through to CINC.
