To see if someone's using your email, check your account's recent activity for unfamiliar devices, IPs, or locations in security settings (like Google's "Your devices"), look for strange emails or login requests, and use HaveIBeenPwned.com to see if your address was in data breaches; if you find suspicious activity, secure your account immediately by changing passwords and enabling 2-Factor Authentication.
Email Checker validates an email address in seconds. It runs 15+ checks, such as email format, DNS, MX records, and SMTP to confirm the address is active and deliverable. Try it for free.
How to find all accounts linked to your Gmail address
You might not realize that someone is using your email address immediately, but there are a few signs to look out for. Hackers don't always take over your account, so it's important to watch for unusual login attempts or friends mentioning suspicious messages you didn't send.
In the "Concurrent session information" section, you'll see if you're signed in to Gmail on another device, browser, or location. In the "Access type" section, you'll see the browser, device, or mail server (like POP or IMAP) that you accessed Gmail from.
The most popular options include: Sender Policy Framework (SPF): SPF automatically checks whether an IP is authorized to send emails from a specific domain. Domain Key Identified Mail (DKIM): Signs all outgoing messages with two cryptographic keys. DKIM also validates incoming messages.
Go to the "Security" page in your Google account settings. Locate the device you want to remove under "Devices you trust." Click on the three-dot menu icon next to the device name, then select "Remove." Google will ask you to confirm removal of the device.
What to do if a scammer has access to your email
Scammers use phrases that create urgency, fear, or excitement, demanding immediate action like "Act now!" or "Don't hang up," and often involve requests for gift cards or Bitcoin, combined with threats of account compromise or promises of huge rewards (e.g., "You've won!") to bypass logic. Key tactics include isolation ("Don't tell anyone"), emotional manipulation (love bombing, family emergencies), and unusual requests to move money in specific ways (Bitcoin ATMs, secret accounts).
Go to your Google Account. Tap Security & sign-in. On the Your devices panel, select Manage all devices. You'll see devices where you're currently signed in to your Google Account or have been in the last few weeks.
The best Gmail trick is plus addressing: you can add +anything after your username (e.g., yourname+shopping@gmail.com) and all mail still goes to yourname@gmail.com, letting you create infinite unique addresses for tracking, filtering, and sign-ups without new accounts. This lets you spot spam (if yourname+weirdsite gets spam) or automatically filter newsletters (using a filter for yourname+newsletters) to keep your main inbox clean.
To find accounts in your name, check your credit reports at AnnualCreditReport.com for credit cards/loans and your ChexSystems report at ChexSystems.com for bank accounts, plus search your state's unclaimed property database (like MissingMoney.com) for forgotten funds, and look for unusual activity in IRS/SSA records for potential fraud. There's no single place, so combine these methods for a comprehensive view of credit, banking, and old accounts.
You know your email is hacked if you can't log in, see strange emails in your Sent folder or deleted from your Inbox, find unfamiliar login alerts (IPs/locations), receive unexpected password reset emails, or if friends get spam from you. Changes to settings like forwarding rules are also red flags, indicating a hacker is trying to lock you out or hide their activity while potentially accessing your other accounts.
Pretend to be an automated messenger.
One of the most satisfying ways to shut down a text scammer is to scam them right back—with a pretend automated message. As a bonus, you can also say that they'll be “billed” or “charged” for your services to really mess with their heads.
Scam red flags include intense pressure and urgency, threats (arrest, utility shutoff), requests for unusual payments (gift cards, crypto, wire transfers), secrecy demands, and offers that sound too good to be true, like guaranteed high returns or huge prizes. Watch for unsolicited contact, generic greetings, poor grammar, and demands for personal information or immediate action, as these signal attempts to manipulate you into acting without thinking, says the FBI and consumer protection agencies https://www.fbi.gov/video-repository/frauds-red-flags-121625.mp4/view, https://consumer.georgia.gov/red-flags-scam,.
How do you know if your email has been hacked? 7 signs to look out for
You shouldn't immediately delete a hacked email; instead, focus on securing it by changing passwords, enabling 2FA, checking settings, and scanning devices, as the account links to many other services; deletion should be a last resort after backing up data, as it can create new issues with address recycling, but create a new, secure email for future use.
Block Malicious Emails with Spam Filter
You may not want to risk opening the email to unsubscribe because it (e.g., a link to unsubscribe) could allow access to a virus or other malware.
Click Edit Google Account. On the left, click Security. In the "Your devices" panel, click Manage all devices. Select a device or session you want to sign out.
To remove a device from your account, go to the security or devices section in your account settings (like Google, Microsoft, or Apple), find the device you want to remove from the list, and select the option to sign out, remove, or unlink it; this logs the device out and removes it from your trusted list.
The steps may look different depending on your device.
