How to check if your email has been hacked
Introduction
Email is the center of your digital life. It connects to your bank accounts, social media profiles, online shopping, cloud storage, work accounts, and much more. If someone gains access to your email, they may also gain access to many of your other online accounts.
Cybercriminals use stolen email accounts to steal personal information, send phishing messages, reset passwords, and commit online fraud. Unfortunately, many people don't realize their email has been hacked until it's too late.
The good news is that hacked email accounts usually show warning signs. If you know what to look for, you can secure your account before serious damage occurs.
In this guide, you'll learn how to identify the most common signs of a hacked email account, how to check your account for suspicious activity, and what to do if someone has already gained access.
10 Warning Signs Your Email Has Been Hacked
1. You Receive Login Alerts From Unknown Devices
Most email providers send a notification when your account is accessed from a new device or location.
If you receive a login alert from a country, city, or device you don't recognize, treat it as a serious warning. Even if the login attempt failed, someone may be trying to access your account.
What to do:
- Check your recent login activity.
- Change your password immediately if the login wasn't yours.
- Enable two-factor authentication (2FA).
2. Your Password Suddenly Stops Working
One of the clearest signs of a hacked email account is when your password no longer works.
Attackers often change the password after gaining access to prevent the real owner from logging in.
If this happens:
- Try your recovery options immediately.
- Reset your password using your recovery email or phone number.
- Don't wait, because every minute gives an attacker more time to misuse your account.
3. Emails You Never Sent Appear in Your Sent Folder
Open your Sent folder and look carefully.
Do you see emails you never wrote?
Hackers commonly use compromised accounts to:
- Send spam
- Deliver phishing emails
- Spread malware
- Scam your contacts
If you notice unknown emails, secure your account immediately.
4. Important Emails Suddenly Disappear
Missing emails are another common warning sign.
Some attackers create filters that automatically:
- Delete incoming emails
- Archive messages
- Forward emails to another address
These changes allow hackers to hide password reset notifications and security alerts.
Check your email filters and forwarding settings for anything you didn't create.
5. Friends Say They Received Strange Messages From You
If family members, friends, or coworkers tell you they received suspicious emails from your address, don't ignore it.
Common examples include:
- Cryptocurrency scams
- Fake invoices
- Prize notifications
- Password reset links
- Requests for money
This usually means your email account has been compromised.
Why Email Security Matters
Your email account is often the master key to your digital identity. If an attacker controls your email, they may be able to reset passwords for other services, read sensitive information, and impersonate you.
That is why checking your email security regularly is one of the most important steps you can take to protect your online accounts.
How to Check If Someone Has Accessed Your Email Account
Simply noticing suspicious activity isn't enough. You should verify whether someone has actually accessed your account. Follow the steps below to investigate your email security.
6. Check Your Recent Login Activity
Most email providers allow you to view your recent sign-in history.
Look for:
- Unknown countries
- Unknown cities
- Devices you don't own
- Browsers you've never used
- Logins at unusual times
If you notice any unfamiliar activity, assume your account may have been compromised.
Tip: If you're unsure about a login, change your password immediately and sign out of all devices.
7. Review Your Recovery Email and Phone Number
Hackers often change recovery information so they can regain access even after you reset your password.
Open your account settings and check:
- Recovery email address
- Recovery phone number
If anything has changed without your permission, update it immediately.
8. Look for Unknown Email Forwarding Rules
One of the most overlooked signs of a hacked email account is hidden forwarding.
A hacker may secretly forward all your emails to another address while leaving your account looking normal.
Check whether:
- Automatic forwarding is enabled.
- Unknown forwarding addresses exist.
- New inbox rules have been created.
Delete any rules or forwarding addresses you don't recognize.
9. Review Connected Apps and Devices
Many users grant third-party apps permission to access their email account.
Go to your account's security settings and review:
- Connected apps
- Trusted devices
- Browser sessions
Remove access for any app or device you don't recognize.
10. Watch for Password Reset Emails
Unexpected password reset emails from banks, social media platforms, shopping websites, or other online services can indicate that someone is attempting to access your accounts.
Even if the reset wasn't completed, treat these emails as a warning.
What To Do If You Confirm Your Email Has Been Hacked
1. Change Your Password Immediately
Create a password that:
- Is at least 16 characters long
- Includes uppercase and lowercase letters
- Contains numbers and symbols
- Is unique and not used on any other website
2. Enable Two-Factor Authentication (2FA)
Two-factor authentication adds an extra layer of security.
Even if someone knows your password, they won't be able to sign in without the second verification step.
3. Sign Out of All Devices
Most email providers let you log out from every device connected to your account.
This immediately removes unauthorized access.
4. Scan Your Computer and Phone
Malware or spyware may have stolen your password.
Run a full security scan using trusted antivirus software and install all available security updates.
5. Change Passwords for Important Accounts
If your email was compromised, also change the passwords for:
- Online banking
- Social media accounts
- Cloud storage
- Shopping websites
- Work or school accounts
Use a different password for each account.
How to Protect Your Email Account From Future Hacks
Recovering your email account is only the first step. The next goal is to prevent hackers from accessing it again. Following these security practices can significantly reduce the risk of future attacks.
1. Use a Strong and Unique Password
A weak password is one of the biggest security risks.
A strong password should:
- Be at least 16 characters long.
- Include uppercase and lowercase letters.
- Contain numbers and special characters.
- Be unique for your email account.
Avoid using:
- Your name
- Your birth date
- Phone number
- Simple passwords like "123456", "password", or "qwerty"
2. Turn On Two-Factor Authentication (2FA)
Two-factor authentication adds an extra security layer.
Even if someone steals your password, they still need the second verification code to sign in.
Whenever possible, use an authentication app instead of SMS for better security.
3. Never Click Suspicious Links
Phishing emails are one of the most common ways hackers steal passwords.
Before clicking any link:
- Check the sender's email address.
- Hover over the link to inspect the destination (on desktop).
- Look for spelling mistakes or unusual requests.
- Never enter your password on a suspicious website.
If something feels unusual, don't click it.
4. Keep Your Devices Updated
Security updates fix vulnerabilities that hackers may exploit.
Always update:
- Your operating system
- Web browser
- Email app
- Antivirus software
Enable automatic updates whenever possible.
5. Review Your Account Security Every Month
Spend five minutes each month checking:
- Recent login activity
- Connected devices
- Recovery email and phone number
- Third-party app permissions
- Inbox filters and forwarding rules
Regular checks can help you detect suspicious activity early.
Common Mistakes That Put Email Accounts at Risk
Many email hacks happen because of simple mistakes.
Avoid these habits:
- Reusing the same password on multiple websites.
- Sharing verification codes with anyone.
- Downloading unknown attachments.
- Ignoring security alerts.
- Using public Wi-Fi without caution.
- Leaving old devices signed in.
Even one mistake can expose your account.
