Holehe online: check where an email is registered
Holehe is a free command-line tool that checks whether an email address has an account on a list of sites. If you don't want to install Python, TraceFind does the same kind of check in the browser, on more sites, with breach data added.
No install needed. Paste an email address and watch the results stream in.
Check an emailWhat Holehe does
Holehe is an open-source Python tool. For each supported site it asks the sign-up or password-reset page whether the email address is known, and prints the sites that answer yes. Its README lists more than 120 sites. It is free, runs locally and is a staple of email OSINT.
The catch: you need Python, a terminal and some patience when modules break as sites change their pages.
Running the same check online
TraceFind's email search runs registration checks on 296 sites in parallel and shows results as they arrive, usually within a minute. Like Holehe, the checks use the same screens a normal visitor sees and never send an email to the address owner. On top of the registrations you get:
- Data breaches the address appears in, with date and exposed data
- The linked Google account, where public
- Whether the mailbox exists, who hosts it and whether it is disposable
- Export as PDF, JSON, CSV or TXT, and an investigation canvas

How to use the results
A registration hit says an account exists, not who owns it. Treat each hit as a lead: open the site's public profile if there is one, compare names, pictures and usernames, and note where details don't match. The email OSINT guide walks through the full method.
No install needed. Paste an email address and watch the results stream in.
Check an emailFrequently asked questions
Is there a Holehe web version?
Holehe itself is a command-line tool. TraceFind runs the same kind of registration check in the browser, on 296 sites, without installing anything.
Does the email owner get a notification?
No. The checks use the same sign-up and recovery screens any visitor sees and don’t send email to the address.
