How often should you check your email for breaches?
2 min read · Updated October 15, 2026
Checking every one to three months is a sensible routine for most people. Check immediately after a company announces a breach, after a phishing scare, before reusing an old address for something important and whenever you create or retire an account.
A simple routine
New breaches are discovered all the time, and old ones keep surfacing. A quick check every few months catches new exposures early without becoming a chore. Tie it to something you already do, such as a seasonal password cleanup.
Check sooner when
- ✓A service you use announces a breach or forces a password reset.
- ✓You receive a suspicious email, text or login alert.
- ✓You are about to reuse an old address for banking, work or a new account.
- ✓A relative, colleague or friend tells you their account was compromised.
- ✓You are cleaning up accounts or switching password managers.
Find out if your email is in a known breach
Run the free Leakill check. No password needed, no signup, and you see the result in seconds.
Do more than check
Regular checks help only if you act on the results. Keep a short list of your key accounts, make sure the important ones use unique passwords and two-factor authentication, and retire accounts you no longer use.
Frequently asked questions
Is once a year enough?+
It is better than never, but more frequent checks catch newly disclosed breaches sooner.
Do I need to check if I already use a password manager and 2FA?+
Those habits make leaks far less harmful, but checking still shows which accounts to clean up.
Should I check my family’s emails too?+
Check addresses you own or manage with the owner’s permission, such as a child’s or elderly relative’s account you help look after.
Stop guessing. Check your email in seconds.
The free Leakill check looks for your email address in known breach records and tells you whether it was exposed. If it was, an optional detailed report lists the incidents, dates, sources, the kinds of data involved and practical next steps. It is a one-off report, not a subscription.
A breach match is a warning signal, not proof that someone has access to your account today. No public database covers every breach, so a clean result lowers risk without guaranteeing safety.
