Know a lead is real before you spend a minute on it.
Fake names, disconnected numbers, and typo emails eat your sales team's day. Lead Verification checks the phone, email, and address on a lead, confirms they belong to the same person, and returns a simple quality score.
Illustration with sample data.
Lead Verification, in plain English.
Lead Verification checks a lead's contact details against live data: whether the phone and email are valid and reachable, whether the address exists, and whether the name on the lead matches the person behind the phone or email. The result is a High, Fair, or Low quality score with the individual checks behind it.
Run one lead by hand, upload a list of up to 50,000 records, or call it from your own systems with an API key so every new form lead is scored the moment it arrives.
What you get
- A High, Fair, or Low quality score per lead
- Phone, email, and address validity checks
- Name-to-phone and name-to-email matching
- Bulk verification with an export of the results
- API access for real-time scoring
