Reverse email lookup

Quick answer

A reverse email lookup starts from an email address and shows what's tied to it in public and lawfully available sources. Serus checks sources including the surface web, social profiles, breach databases, paste sites and dark web datasets in one pass, and links every finding to the source it came from.

What it finds

  • The breach dumps and credential collections the address appears in, with passwords and other sensitive values redacted until you choose to reveal them
  • Accounts and profiles connected to the address across social profiles and specialist OSINT sources
  • Other identifiers tied to the same details, such as usernames and domains
  • For a business sender, whether the domain is a lookalike registered days ago rather than the real company's
  • The source of every finding, so you can check the whole picture yourself

How it works

  1. 1

    Enter the email address

    Paste the address, or ask in plain language ("Who sent this invoice?"). Add a username or domain if you have one.

  2. 2

    Serus searches many sources at once

    Sources including the surface web, public records, social profiles, breach databases, paste sites and dark web datasets, in a single pass.

  3. 3

    Review the connected results

    Identifiers are cross-referenced into one profile, each finding linked to its source, with a low tolerance for false positives.

  4. 4

    Decide what to do next

    Confirm a payment change by phone before you wire, walk away from a seller, or rotate the passwords that leaked.

Frequently asked

What is a reverse email lookup?

A search that starts from an email address instead of a name. It shows the accounts, breach records and other identifiers tied to the address, so you can tell whether a sender is who they claim to be.

Can I look up my own email address?

Yes. Searching your own address shows which breaches it appears in and what's connected to it, so you can change exposed passwords and see what a stranger could find.

Is a reverse email lookup legal?

Working with publicly available information is legal in most places, but how you use it is governed by law. You need a legitimate reason, like fraud prevention or safety. Never use it for stalking or harassment, or for hiring, tenancy, credit or insurance decisions.

Is what I search private?

Yes. Nothing you search is used to train AI models, data is encrypted in transit and at rest, and we never sell your data. Serus doesn't contact the subject of a search.
