Is My Email Compromised? How to Check and What to Do

This distinction matters.

Email exposure means your address may have appeared in information obtained from a breach or another data exposure.

Email compromise means someone actually gained unauthorized access to your account.

An address can be exposed because you used it on a completely unrelated website.

For example, you might create an account with an online store using your primary email address. If the store later suffers a data exposure, your email could appear in that data even though your email provider itself was never compromised.

That is why a breach result alone cannot tell you whether someone is reading your inbox.

Look inside the account itself.

Warning signs include:

The FTC recommends checking forwarding rules, sent messages, deleted messages, recovery information, and active devices after unauthorized access is suspected.

One suspicious notification does not always prove compromise, but several of these signs together deserve immediate action.

Go directly to your email provider's official website or app.

Look for sections such as:

Pay attention to the combination of device, time, browser, and location.

Location alone can sometimes be misleading because mobile networks, VPNs, and internet providers can make legitimate activity appear to come from another place.

An unfamiliar device combined with activity at a time you know you were not logging in is more concerning.

This is one of the easiest signs to miss.

Someone who gains access to your inbox may configure mail to automatically forward to another address.

That can allow them to continue receiving messages even after other security changes.

Delete anything you did not create.

The FTC specifically advises hacked-email victims to inspect forwarding settings because unauthorized rules can send copies of their messages elsewhere.

Check the recovery email address and phone number attached to your account.

Both should belong to you.

If someone changes recovery information, they may be able to regain control later even after you replace your password.

Also review trusted devices or authentication methods.

If there is evidence of unauthorized access, secure the account immediately.

Change the password.

Use a completely new password.

Do not reuse it on another website.

NIST recommends password managers because they can generate and store unique credentials for different accounts.

Sign out other devices.

Use the provider's option to remove unfamiliar sessions.

If unauthorized access seems likely, signing out all other sessions can force anyone using an existing session to authenticate again.

The FTC recommends signing out of all devices after recovering a hacked account.

MFA adds another requirement beyond your password.

Even if someone obtains the password, the additional factor may prevent access.

NIST explains that MFA provides another layer of protection when a password is compromised.

Consider a passkey.

Where supported, passkeys can reduce reliance on reusable passwords.

NIST notes that passkeys use unique digital credentials and are substantially more resistant to phishing than ordinary passwords.

Your email is often the recovery channel for other accounts.

Someone controlling your inbox may be able to request password resets for:

and receive the reset messages themselves.

The FTC specifically highlights this chain of risk when explaining why email accounts deserve strong protection.

Secure your primary email before less important accounts.

That is a much better situation.

If a checker indicates exposure but your account activity looks normal:

Exposure should be treated as information that helps you decide what to protect.

It is not automatic evidence of account takeover.

Those situations require different responses.

A positive exposure result does not prove unauthorized access.
