What to Do If a Scammer Has Your Email Address
Published:
You probably don’t give your email address a second thought. But it’s a surprisingly valuable piece of information—and it can cause trouble in the wrong hands.
This article examines how scammers can use your email address, the warning signs of a compromised account, and the simple steps you can take to keep your inbox secure.
What Can Someone Do With Your Email Address?
A hacker or scammer knowing your email address alone isn’t usually enough to compromise your accounts or steal your data. However, it does give them a foothold from which they can launch more sophisticated attacks. Here’s how they might leverage this seemingly basic information:
Look up your email in data breaches
Scammers can search data breach databases and the dark web for your email address to see if your passwords or other sensitive details have been exposed.
With this information, scammers can gain access to your online accounts and sensitive information.

Impersonate you via email spoofing
Scammers can masquerade as you by spoofing your email address, making their fraudulent messages appear as though they genuinely come from you.
This tactic can fool your friends, family or colleagues into believing they’re talking to you, making them more likely to fall for scams.
Send you phishing emails
Phishing emails trick you into revealing sensitive information or installing malicious software. They often look like legitimate communications from trusted sources, increasing the likelihood of falling victim to a scam.
If a hacker knows your email address, they could send you phishing emails to obtain more valuable information.

What to Do If a Scammer Has Your Email Address
If you think your email address has been leaked, acting quickly is essential to minimize potential risk. Here are some steps you can follow:
Don’t reply to any messages
Scammers might try to engage you in a conversation to extract more personal information or gain your trust.
Avoid responding to suspicious messages, even if they seem to come from someone you know. Notify your contacts to ignore these emails and not interact with the sender.
Change your email password and security questions
If you suspect your email address has been exposed in a data breach, it’s crucial to strengthen your account security immediately. Update your email password to a strong, unique combination that you don’t use elsewhere. Consider using a passphrase that’s easy for you to remember but difficult for others to guess.
While you’re updating your password, review and change your security questions as well. Choose answers that aren’t easily discoverable through social media or public records—consider using unrelated responses that only you would know.
Pro Tip: Use a password manager like NordPass to save all your passwords in a safe place.
Report phishing scams to email providers
Reporting phishing emails can help your provider block the sender and protect others from falling victim.
Use your email service’s built-in tools, like Gmail’s “Report phishing” option, to flag suspicious messages and improve overall security.
Customize email spam filters
Update your email’s spam filter settings to prevent future phishing and spam attempts.
Block known unwanted senders and configure your filters to automatically redirect emails with specific keywords or domains to the spam folder.
Remove information from people-search sites
Hackers often use people-search sites to gather personal details like your address, phone number, or relatives.
To reduce your exposure, remove your data from sites like Whitepages or BeenVerified by using their opt-out options.
Pro Tip: It’s also a good idea to request that data brokers remove your information from their databases.
Enable multi-factor authentication (2FA)
Adding an extra layer of security makes it harder for hackers to access your account, even if they have your password.
Enable 2FA on your email and other accounts for added protection using authentication apps like Google Authenticator or Authy.
Scan for viruses and malware
When your email is exposed in a data breach, you become a more likely target for sophisticated phishing attacks. Hackers may send you personalized malicious emails designed to trick you into downloading malware.
As a precaution, run a comprehensive scan of your devices using reliable anti-malware software. This helps detect and remove any threats that might have already infiltrated your system through targeted phishing attempts.
Certo’s mobile security solutions are excellent options for detecting and removing malware on smartphones, while traditional antivirus programs can secure your computers and laptops against these targeted threats.

Consider creating a new email address
If you find yourself inundated with phishing attempts or receiving alerts about repeated login failures (which could indicate someone trying to brute force your password), it might be time for a fresh start with a new email account.
What is a brute force attack?
A brute force attack is a hacking technique used to gain unauthorized access to a system, account, or encrypted data by systematically trying all possible combinations of passwords, encryption keys, or credentials until the correct one is found.
It relies on trial and error rather than exploiting software vulnerabilities.
While this is a more dramatic step, a clean break can significantly reduce your security headaches when your current email address has become a persistent target for attackers.
Set up a new, secure email account with a strong password and 2FA. Update all your important online accounts to use the new email address, and gradually phase out the old one as you transition your digital presence.
Signs Your Email Account Has Been Hacked

Here are some common warning signs that your email account may be compromised:
You can’t log in
- What to look for: Being locked out of your account, even though you’re sure you’re using the correct password.
- Action: Attempt to reset your password immediately. If the reset link doesn’t reach you, it’s possible the hacker changed your recovery information.
Unfamiliar login activity
- What to look for: Emails notifying you of logins from unfamiliar locations or devices.
- Action: Check the login activity in your email settings. Most providers, like Gmail or Outlook, show a history of recent logins.
Seeing strange emails in your inbox
- What to look for: Suspicious emails in your Sent folder that you didn’t write, often containing suspicious links or requests for money.
- Action: Notify your contacts immediately to avoid them falling for scams.
Increased spam in your inbox
- What to look for: A sudden spike in spam or phishing emails could mean your email address has been leaked or compromised.
- Action: Use tools like Certo’s breach check to see if your email is part of a data breach.
Complaints from your contacts
- What to look for: Friends, family, or colleagues report receiving strange or inappropriate emails.
- Action: Alert your contacts not to click any links and secure your account.
Recovery information has changed
- What to look for: Notifications that your recovery phone number, backup email, or security questions have been updated without your knowledge.
- Action: Immediately contact your email provider for account recovery and assistance.
Suspicious auto-forwarding rules
- What to look for: Hackers often set up rules to forward your incoming emails to themselves, keeping you unaware of suspicious activity.
- Action: Check your email settings for forwarding rules you didn’t create.
Account activity shows unauthorized changes
- What to look for: Settings like your display name, email signature, or linked apps have been altered.
- Action: Review and undo changes and secure your account.
Failed Login attempts
- What to look for: Notifications of failed attempts to log in to your account.
- Action: This suggests someone is trying to guess your password—update it to something more secure and ensure two-factor authentication is enabled for your account.
What Happens If Someone Hacks Your Email Account?
Exploit information for social engineering attacks
By accessing your hacked email account, scammers can gather personal information to manipulate you or your contacts.
These social engineering tactics may involve convincing you to transfer money, share passwords, or perform other actions that seem logical but are fraudulent.
Gain access to other accounts
Email is the key to resetting passwords and verifying accounts. If a scammer gains access, they can infiltrate other platforms you use, from social media to banking apps.
This makes securing your email with a strong password and two-factor authentication essential.
Spam your contacts
If scammers gain control of your email, they can send potentially dangerous emails to your contacts. These emails might contain malicious links or scams, potentially jeopardizing your relationships and causing others to distrust your emails.
Compromise two-factor authentication (2FA)
Email-based 2FA is a critical security measure, but if a scammer has access to your email, they can intercept one-time passwords or even change the 2FA settings. This could lock you out of your email and other online accounts entirely.
Potentially blackmail you
Sensitive information found in your email can be used for blackmail. Scammers might threaten to expose private details unless you comply with their demands.
Target your work email
Personal emails often contain job-related information. If a scammer uncovers details about your workplace and other online services you use, they could attempt to breach your professional accounts or compromise your company’s security.
How Hackers Can Use Your Email to Steal Your Identity
The good news is that having your email hacked doesn’t automatically mean you’ll become a victim of identity theft. However, it’s still a serious risk you shouldn’t ignore.
When scammers access your email, they can dig through your inbox and discover sensitive details about you.
This information can be combined to impersonate you, commit fraud, or access your other accounts. Here are some ways an email hack could lead to identity theft:
- Invoices and receipts: Hackers may find receipts or bills in your email that display your name, address, and phone number—details that can be used to create fake accounts or impersonate you.
- Financial information: Emails containing banking details, credit card numbers, or payment confirmations can provide scammers with the means to commit financial fraud.
- Sensitive documents: Scammers may uncover attachments, photos, or sensitive accounts that contain personally identifiable information (PII), such as Social Security numbers, passport details, or driver’s license numbers.
- Private photos or messages: Personal information shared through emails, even casual exchanges, could be exploited for blackmail or to impersonate you.
- Account recovery information: Many services use email for password recovery. A compromised email can be a gateway for hackers to reset passwords and access your bank accounts, social media, or other critical services.
