What is an email leak check?
An email leak check is a free tool that compares your email address against databases of known data breaches. If your address turns up, it means a company you trusted with your email was hacked or leaked its data — exposing information tied to your account, sometimes including your password. You may also see it called a leaked email check or an email breach checker; it does the same thing.
EmailLeaked checks your address against 1019+ known breaches in about two seconds and translates each result into plain English: what was exposed, how serious it is, and exactly what to do next. Your email is never stored, and you never need an account.
Finding your email in a leak is common and it is not your fault — you did nothing wrong. It means a company failed to protect data you gave them. What matters is what leaked alongside your address. If a password was exposed, change it everywhere you used it. If only your email address leaked, the realistic risk is more spam and phishing rather than someone getting into your accounts.
You can also browse the breaches we track to see which companies have leaked data and what was exposed in each one.
Frequently asked questions
How do I check if my email has been leaked?
Enter your email address in the box at the top of this page. It is checked against known breach records in about two seconds and then discarded — nothing is stored. You will see which breaches your address appeared in, what data was exposed in each, and what to do first. There is no signup and no payment.
What does it mean if my email was leaked?
It means a company that held your email address was breached and its data was exposed. It does not mean your inbox was hacked, and it is not something you did wrong. What matters is what leaked alongside your address — if a password was included, change it everywhere you used it. If only your email address leaked, expect more spam and phishing rather than account takeover.
Is it safe to check my email here?
Yes. Your email address is checked in real time and discarded immediately — it is never stored, logged, shared, or sold. There is no signup, and your address is never sent to advertisers or third parties.
What should I do if my email was found in a breach?
Change the password on the affected account first, then change it anywhere you reused that password. Turn on two-factor authentication and stay alert for phishing emails that use your leaked details. Our after-breach checklist walks through every step in order.
Does a breach mean my email account was hacked?
Not usually. A breach means a company that stored your email address was hacked or leaked its data — not that someone broke into your inbox directly. But if your password was exposed in the same breach, your account is at real risk, which is why checking matters.
How often should I check my email for breaches?
New breaches surface almost every week, so a single check is only a snapshot in time. Checking about once a month is a good habit, and you should always re-check after a service you use announces a breach.
Is the email breach checker really free?
Yes — it is free with no signup, no trial, and no payment required, now or later. The site is supported by optional ads and security-tool recommendations, not by charging you to check.
Where does the breach data come from?
We aggregate records from industry-standard breach data sources covering 1019+ known breaches and billions of exposed records. Each result shows what data was exposed and how serious it is, in plain English.
