From an Email to a Full Digital Footprint
Validity & Deliverability
Verify that an email address is real, properly formatted, and deliverable. Detect disposable addresses, role-based accounts, and catch-all domains.
Breach Exposure
Check whether the email has appeared in known data breaches or leaked credential databases. Use this signal as a high-priority risk indicator.
Domain Risk Scoring
Analyze the email domain for disposable providers, newly registered domains, spam history, and domain age. Returns a normalized risk score.
Linked Social Profiles
Discover social media accounts, forums, and public web presence connected to the email address. Useful for identity verification and OSINT.
Identity Confidence
Returns a composite confidence score (0–10) based on the breadth and consistency of signals found. Higher scores indicate more verifiable identities.
Marketing Hygiene
Validate contact lists, detect invalid addresses, and filter high-risk domains before outreach. Improves deliverability and CRM data quality.
