[04] Overview

Holehe online: the free email OSINT and reverse email lookup tool

Holehe is a free email OSINT tool that runs entirely online, no install, no API key, no command line. Paste any email address and Holehe performs a live reverse email lookup across 200+ websites and social networks, then returns one report of every site the address is registered on. It is the browser version of the open-source Holehe project from GitHub, rebuilt as an online OSINT tool you can run from any device.

Whether you need email OSINT, a reverse email search, a Gmail lookup or a way to find the social media linked to an email address, it is the same engine in one place. Every check reads only public sign-up signals, so Holehe can verify an email address without ever sending an email to it.

  • Reverse email lookup

    Run a reverse email lookup or reverse email search from a single address and find every account and platform linked to it, the modern reverse email lookup tool security teams actually use.

  • Email OSINT checker

    A full email OSINT checker and osint email lookup in your browser: search an email address across 200+ sites and read an osint email report broken down by category.

  • Find social media by email

    Find social media by email in seconds. Holehe is a free social media lookup by email that surfaces the accounts linked to an email address across the platforms that matter.

  • Gmail lookup

    Use Holehe as a Gmail lookup: look up a Gmail address or any inbox, including a reverse email lookup for Gmail, to see where that email is registered online.

  • Search by email address

    Search by email address to map a digital footprint, a people-search-by-email primitive that returns platforms, not paywalls. See where an email leads next.

  • Verify email without sending

    Verify an email address without sending an email. Holehe only reads each site's public sign-up response, so the lookup stays silent and the owner is never notified.
