How Can I Tell if Someone’s Reading My Email?

It can be difficult, if not impossible.

It can be very difficult -- perhaps impossible -- to determine if your mail's being read before you get to it.

Question: How do I know if someone is opening my email before I read it, then marking it as unread?

Ultimately, you don’t.

TL;DR:

Someone's Reading my email?

It’s almost impossible to know whether your email has been read and marked unread before you get to it. The only true solution is to prevent that access in the first place with good account and computer security. Encrypting your sensitive content is another approach.

Online services

This scenario you might be thinking of is this:

  • Someone somehow gains access to your online email account.
  • They sign in as you and read your email.
  • Before they exit, they mark the messages they’ve read as unread.
  • They do not change your password or otherwise hack your account.

There’s really no way to tell if this has happened.

Some email services, like Gmail and Outlook.com, have account access histories that might tell you that your account had been signed in to, and from where, but it will not tell you what was done during the access.

You can prevent this scenario by maintaining proper account security, including two-factor authentication, to prevent unauthorized account access.

Desktop (and mobile) email programs

The equivalent scenario on a computer or mobile device is this:

  • Someone gains access to your computer or phone.
  • They open your email program and read your email.
  • Before they exit, they mark the messages they’ve read as unread.
  • They do not change your account password or otherwise hack your account or computer.

Once again, there’s really no reliable way to tell that this has happened. Like online account access history, you may be able to find information in the event log about when your computer was being accessed, but that’s not guaranteed, is extremely complex, and won’t tell you what was actually happening during the access.

The only scenario that could possibly help is to pre-emptively install a keystroke logger or other type of monitoring software on your own machine. You would then be able to review the logs to see what may have been happening.

You can prevent this scenario by keeping your PC secure — either physically, by locking it up, or by making sure you always sign out of Windows and require a password to get back in.

The email system

This is the scenario most people don’t think about. It’s short.

  • Someone at your email provider, or at the email provider of your correspondents, reads your email while it’s stored on their servers.

“Someone”, in this case, could be a rogue employee of the service with sufficient access, or it could be law enforcement showing up with a court order.

There’s no way to prevent this. The good news is that unless you’re involved in activities your government might not approve of, it’s exceptionally rare.

Do this

Aside from keeping your online accounts and your computer secure, this is generally not something I would worry about. Of course, if you are a high-value target, you may feel otherwise.

The only proper solutions are:

  • Use a communications medium that is more secure than email.
  • Encrypt your email so that no one else can access it.

  1. I have microsoft outlook email at my school. I think someone is reading my email. Can the server or administrators see which computer is accessing my account or if someone is doing it online by the exchange? Thanks.

  2. I have a client(CFO, CEO) who is having issues with information being passed to outside people.

    They need to determine if the admin person is passing out the information. We know how to stop it but must determine and confirm whow the problem is.

    Is there software that can not be detected on the desktop that can determine id e-mail has been opened and passed on?

  3. There are things such as keyloggers that may help. But realize that any software installed can be detected … it’s just a matter of how difficult it is to detect. Anyway, this site has pointers to packages – mostly aimed at parents, but the concept is the same: http://www.safetysurf.com/

  4. I think someone is in my email at my school account. Is there any way I can get them to monitor it and tell me exactally who it could be?

  5. I think someone is using spyware to look into my email. I tried one of those free spy ware scanners and it said that it found 4. It said that I had 2 Alexa adware and 2 CWS. Does that free scanning stuff really work? And if so how do I get rid of it and what exactly is the difference between the two.

  6. i have an msn email account as well as a juno account. if someone is trying to guess my password and get into my email without me knowing is there any way msn will know and notify me? I have purposely entered the incorrect password several times to see what happens and it just tells me i have made too many attempts with the wrong password and that my email is temporarily unavailable. is there any way of finding out if someone is trying to get into it and then finding out who it is?

    Reply
  7. is there any way i can find out how many times a day i (in my case i or anyone else) get into my Yahoo! mail account?? I’m pretty sure someone is but lack proof (and it’s not from my computer).

  8. Hi- I think someone has access to my earthlink email account and has been checking my email. Is there anyway possible to trace their IP address or find out who is checking my email? This is a huge security issue so if I notified police is there anything they would be able to do?

    Reply
  9. I sent an e-mail to someone and realized I didn’t want to send it. I guessed her password and logged into her yahoo account to delete it before she could read it. She read it, but I deleted it anyways so she couldn’t forward it. Is their anyway if she suspects someone was in her e-mail that she could trace it back to me? I feel ****** for doing that. Thanks!

  10. The practical answer is no. You would have to convince the folks at Hotmail to help you, which is highly unlikely unless you involve law enforcement.

  12. My b/f and I share a computer together. Is there any way he can look on the computer thru the ip address to see what sights I have been on? And also,is there any way he can read my e-mail thru my ip address?

  13. Today when I signed in with my username and password, hotmail rejected my password many times. I remembered my friend has my password. Is it possible that she was checking my email account while I was trying to log on at the same time? after i tried logging on many times then I finally was able to log on. Do you think she changed my password and changed it back? what would have happened if we were both checking at the same time? I have now changed my password.
    thank you.

  14. I’ve had the same problem, except that I have not shared my password with anyone else. Is it possible for someone to gain access without a password?

  16. Any sort of computer expert (i.e. IT, MIS, Computer Science people) are knowledgeable about this stuff. They know how to tinker with computers. Never ever share a computer with a computer junkie. I don’t how it works, but I know there’s a way to record every key that gets typed on a computer. If you share a computer with another person, that person can easily set the computer to record all keys which are being punched into the keypad. The person can then discover your email password.

  17. I just remembered…. they’re called ‘keyloggers.’ Anyone can download keylogger software onto their computer, then record all typing and program information

  18. I am the office manager and we have Outlook at my work. I have a strong suspicion that one of the admins we laid off a couple of weeks ago is checking some of our office emails from her home computer. Could our IT person find out for sure if and when this is happening, maybe through tracking the IP address? How much effort would this take, and if so, could we bring legal action against this person?

  20. It really depends on how the network is set up, but yes, in most cases a competant IT peson could set up some kind of monitoring to see what’s happening.

    I can’t speak to the “legal action” question – I’m not a lawyer.

  25. How do I recoup professionally after someone was monitoring my emails and read what I thought were deleted emails to another colleague that were written in frustration about her? Especially since she had written several disparaging emails about our boss in frustration, however; I had deleted them and would have not ever used them in a retaliatory manner.

  35. folks, if you are using outlook for your email, you can assign “delegates” and give “permission” to open your outlook email. I view my boss’ email daily. go to your outlook help and type in delegates. Someone probably is viewing and using your email account.

    That is not true for most people using Outlook in homes and small businesses. That’s a feature of Exchange Server, typically used in larger companies.
