CheckMate.bio

CheckMate.bio is a reverse email lookup and digital-footprint tool. Enter any email address and it searches public sources for registered accounts across more than 800 online services, including social networks, dating sites, gaming platforms, forums, finance, shopping, professional, and developer services.

Results are grouped by category so the overall footprint is visible at a glance. Each match includes a confidence band — near-certain (80%+), likely (50–80%), or weak signal (below 50%) — to indicate how reliable the finding is. Searches typically complete in under 2 minutes.

A free tier shows basic account presence grouped by category. A one-time $0.99 unlock (via PayPal, no subscription) reveals the detailed report: names, usernames, display names, locations, photos, bio text, last-active dates, and direct profile URLs where publicly available. A $2.99 bundle of 5 detailed searches is also available. Detailed reports can be exported to PDF.

Common use cases include relationship verification, due diligence on a business partner or job candidate, personal security audits (finding where your own email is registered so you can close stale accounts), lead enrichment, and supplementing background checks with a digital-footprint layer.

CheckMate.bio only aggregates publicly observable account metadata and breach-derived public indexes — it does not return passwords or private messages. Users are responsible for complying with local law when querying addresses they do not own.
