Frequently asked questions

Can you tell me who owns an email address?

No. We don't attempt to identify people. This tool focuses on scam signals and phishing patterns linked to the address.

Why might an email be flagged as risky?

Common reasons include impersonation attempts, phishing links, fake invoices, or reports from other users.

Are email lookup pages indexed by Google?

No. Email results are private by design and aren't indexed by search engines or included in our sitemap.

What if my email is flagged by mistake?

You can submit a dispute or report an error from the page. We review reports and adjust where appropriate.

Do you track who searched for an email address?

No. We don't publish or expose who searched anything. Only aggregated safety signals are shown.
