Ocrspace email verification with BillionVerify
OCR.space is a developer-friendly API that converts images and scanned documents into machine-readable text. When your OCR pipeline extracts email addresses from documents, BillionVerify ensures those addresses are valid before they flow into any downstream system, saving you from storing and mailing bad data.
Why verify before the send
Text extracted from scans and images is inherently noisy — OCR errors, legacy data, and informal document formats all produce malformed or outdated email addresses. Verifying every extracted address with BillionVerify before storage or outreach prevents bounces, protects sender reputation, and keeps your database clean.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Ocrspace sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

How it works
- 1
Integrate BillionVerify after your OCR.space API call using the n8n community node, Integrately, or the REST API.

After OCR.space returns extracted text, parse out email-shaped strings and send each to BillionVerify.
- 3
BillionVerify performs SMTP-level checks, disposable domain detection, and syntax validation.
- 4
Suppress or flag any address that fails verification before writing to your database or triggering outreach.
- 5
Log verification results alongside OCR confidence scores for auditing and quality control.
When to use this
Validate emails parsed from scanned business cards
Business-card scanning pipelines often feed CRMs directly. Running each OCR-extracted address through BillionVerify before the CRM write catches misprints and typos so sales teams only work verified contacts.
Sanitise emails extracted from uploaded forms
Paper forms digitised via OCR.space may contain handwritten or faded addresses. BillionVerify validates each one before it enters your email platform, cutting bounce rates on follow-up campaigns.
FAQ
Can I verify multiple emails extracted from a single document?
Absolutely. Send each extracted address to BillionVerify individually via the REST API, or batch them in a single bulk request — results come back per address so you can handle each one appropriately.
How does BillionVerify handle addresses with OCR-induced typos?
BillionVerify checks whether the domain exists and the mailbox accepts mail. A typo that produces a non-existent domain or mailbox will be marked invalid, preventing it from polluting your contact list.
Is there a free tier to test the integration?
BillionVerify offers a free trial so you can verify a batch of OCR-extracted addresses and confirm accuracy before committing to a paid plan.
