How it works
Three steps. Five minutes. No more emails going nowhere.
Step 1 → UPLOAD
Drop your list. The fox gets to work.
Whether it's 100 addresses or 100 million — upload a CSV, connect via API, or sync directly from your ESP. Any format. Any size. No prep work required.
Step 2 → Verify
9 checks. Real answers - not 'unknown.'
Other tools hit a catch-all domain and shrug. VeriFox runs an AI confidence score on every address other tools can't figure out — and gives you a real answer on every single one.
Step 3 → Export
Send only to people who actually exist.
One clean CSV. No ZIP files. No manual sorting. Push directly to your ESP and start sending — to a list that's actually been verified, not just checked.
