Clearbit email verification with BillionVerify
Clearbit enriches contact and company data so your sales and marketing teams can act on better intelligence. Pairing it with BillionVerify ensures the email addresses you enrich and pass downstream are deliverable, keeping your outreach lists clean and your sender reputation intact.
Why verify before the send
Enriched contacts are only valuable when their email addresses actually work. Invalid, disposable, or role-based addresses mixed into Clearbit-enriched lists drive up bounce rates and erode domain reputation. BillionVerify filters these out before they reach your CRM or outreach sequences, protecting every campaign that depends on Clearbit data.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Clearbit sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

}Workflow templates with Clearbit
Ready-to-use workflows that verify emails before Clearbit sends.
How it works
- 1
Connect Clearbit and BillionVerify in n8n using the BillionVerify community node, or link them via Integrately with a single click.
- 2
Trigger verification whenever Clearbit returns an enriched contact — in real time or as a batch from an existing list.
- 3
BillionVerify checks each email for deliverability, disposable domains, role addresses, and catch-all status.
- 4
Contacts that pass verification flow into your CRM or outreach tool; invalid addresses are flagged or discarded.
- 5
Monitor verification results over time to maintain a consistently clean pipeline.
When to use this
Validate enriched leads before CRM entry
When Clearbit enriches a new lead, route the email through BillionVerify first. Only store contacts with deliverable addresses, preventing bad data from polluting your CRM and skewing conversion metrics.
Protect outbound sequences from bounces
Before passing Clearbit-enriched prospects to your sales engagement tool, verify each email. Removing invalid and catch-all addresses keeps bounce rates low and preserves the domain reputation that powers your entire outbound operation.
FAQ
Does BillionVerify work with Clearbit Enrichment and Clearbit Reveal?
Yes. You can verify emails from any Clearbit product — Enrichment, Prospector, or forms — by routing the output through BillionVerify via n8n, Integrately, or the REST API before storing or sending.
What types of addresses does BillionVerify catch?
BillionVerify detects invalid addresses, disposable email domains, role-based addresses (info@, support@), and catch-all domains where deliverability cannot be confirmed, giving you a full risk picture.
Can I verify a large Clearbit export in bulk?
Absolutely. Upload a CSV export from Clearbit to BillionVerify's bulk verification endpoint or process records in batches through the REST API. Results are returned with per-address status codes.
