Lusha email verification with BillionVerify
Lusha is a B2B contact intelligence platform that helps sales and marketing teams find verified business emails and phone numbers for prospects. Pairing Lusha with BillionVerify adds a second layer of email validation, confirming that enriched contact data is deliverable before it enters your outbound sequences.
Why verify before the send
Even data from trusted enrichment providers can include addresses that have changed after a job move, belong to role accounts like sales@ or info@, or sit behind catch-all domains. Running Lusha-enriched contacts through BillionVerify before outreach eliminates hard bounces, protects your sending infrastructure, and improves the accuracy of your campaign metrics.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Lusha sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Lusha
Ready-to-use workflows that verify emails before Lusha sends.
How it works
- 1
Set up an automation using n8n, Integrately, or the BillionVerify REST API to receive Lusha-enriched contact records.
- 2
Extract the email field from each enriched contact and submit it to BillionVerify for validation.
- 3
BillionVerify evaluates the address against MX records, mailbox existence, disposable domain lists, and catch-all detection.
- 4
Contacts passing verification are pushed to your CRM or outreach tool; those flagged as invalid are held back or marked for manual review.
- 5
Use BillionVerify's reporting to track enrichment quality over time and adjust your Lusha filters accordingly.
When to use this
Enriched Lead Verification Before Sequencing
After Lusha enriches a prospect record with a business email, pass it through BillionVerify to confirm the address is active and not a catch-all. Only confirmed deliverable contacts enter your sales sequence, keeping bounce rates near zero.
Bulk List Cleaning After Lusha Export
When exporting a large batch of enriched contacts from Lusha, submit the list to BillionVerify for bulk validation. Remove invalid, disposable, and undeliverable addresses before importing into your CRM or email platform.
FAQ
Why should I verify emails that Lusha already claims are valid?
Enrichment providers validate addresses at the time of data collection, but emails change — people switch jobs, accounts get deactivated. BillionVerify performs a live check at the moment of use, catching addresses that have gone stale since enrichment.
What is a catch-all domain and why does it matter for sales outreach?
A catch-all domain accepts all incoming mail without confirming individual mailboxes exist. Sending to these addresses risks silent drops or soft bounces that inflate your apparent deliverability while reducing actual reach.
How does this integration work technically?
You can connect Lusha and BillionVerify via n8n workflows, Integrately one-click automation, or direct REST API calls from your sales stack. No custom code is required for the no-code options.
Can I set up automatic verification for every new Lusha contact?
Yes. Using n8n or Integrately, you can trigger BillionVerify automatically whenever Lusha adds or enriches a contact, creating a fully automated quality gate with no manual steps.
