How to Verify Your Woodpecker.co List in 3 Steps
1. Prepare Your Prospect File (CSV or Multi-Tab Excel .XLSX)
Gather your scraped or enriched B2B prospect lists before uploading them to Woodpecker campaigns.
2. Verify via KaijuVerifier Bulk Cleaner or REST API
Our engine resolves MX records, fingerprints Exchange Online / Google Workspace / Proofpoint / Mimecast gateways, and verifies each mailbox via TLS 1.3 SMTP.
3. Segment Valid vs. Catch-All Prospects
Import 100% Valid prospects into your primary Woodpecker campaigns, and route high-score Catch-Alls to secondary burner domains.
Use our REST API (POST /api/v1/verify-single) in Make, Zapier, or n8n to verify prospects before pushing them to Woodpecker’s /rest/v1/add_prospects_campaign endpoint.
curl -X POST https://kaijuverifier.com/api/v1/verify \
-H "Authorization: Bearer kv_live_your_api_key" \
-H "Content-Type: application/json" \
-d '{"email": "{{Email (Woodpecker Prospect CSV/XLSX)}}"}'
