How do I send an email so that the recipient cannot identify who I am?
Sending anonymous email is both easy, and incredibly difficult. It
depends on just how anonymous you want to be, and who you’re hiding your
identity from.
And, of course, how paranoid you want to be.

I do want to start by saying that I’m not going to get into the morality or
social implications of anonymous email. Like any technology it can have an
incredibly important role in society and it can be horribly misused. As can the
techniques used to break it.
I’ll start with what I’ll call “anonymous light”. As we’ll see shortly, this
will keep your identity safe from casual or non-technical observers, who are
not likely to pursue it very far.
The short answer is to use a free email account like Hotmail or Yahoo mail,
and make up all of the information required when you create it. Use a false
name and create a completely false identity. Then send your message from that
account.
Most people will be unable to determine from the email messages sent from
that account anything more than that false identity you’ve created.
I call that “anonymous light” because of that term “most people”. In fact,
the email probably could be traced back to you or your machine, but typically
only if people are willing to involve law enforcement if they believe you’ve
done something illegal. The information kept by your ISP and the free email
service, when combined, could provide a trail to your door, but they won’t give
that information without a legal requirement.
It’s important to note that I’m assuming a “reputable” ISP
and free email service. Most are, but obviously if they are willing to give that information
to just anyone, all bets are off. Similariy laws and practices vary from country
to country, so just how easy it is for law enforcement, a private investigator,
or some other entity to get this information may vary greatly depending on where you are,
and where your recipient is.
Now, if your recipient is very internet savvy, he could compare the IP address
from which an email was sent to an IP address known to be you. Because not all
free email services include the originating IP, and in common cases your IP may
change often, this actually only works infrequently. If it does, however, it’s
at least an additional clue that a recipient could gather that could lead them
to you, or perhaps bolster their case if they do take it to law
enforcement.
anonymity’ on the internet.”
Now, unless you are doing something illegal like some form of
online harassment, that “anonymous light” approach may well be enough.
But what if it’s not? What if, for example, you’re a corporate whistle
blower and are concerned that the company might manufacture a case that would
cause law enforcement to track you down?
As we’ve seen, if you log in to your anonymous free email account from your
home computer and send an email, the free email service may have a record of
that. Using your IP and the time you logged in, your ISP could then identify
you. Important: you cannot get this information. But
if the information has been kept law enforcement can.
So step one might be to use someone else’s computer.
And here’s where we start verging on the “just how paranoid are you”
question. Is there any way that you could be traced to having used that
computer at a particular time? Public library computers are nice and all, but
… are there security cameras? Do you have to somehow register to gain
access?
Perhaps an anonymization service, such as Anonymizer would be a good
approach. You might access your free email account through the anonymous proxy,
so that the email would not be directly traceable to you or your machine.
But anonymization services are just that – services run on computer servers.
Do they keep logs? Would those logs be available for inspection if law
enforcement came with the appropriate authority? Maybe. Even if not, (and
here’s the paranoia thing again), with enough resources, it could be possible
to monitor the traffic to and from the anonymization service and “reverse
engineer” who’s sending what. A complex anonymization service could certainly
make this extremely difficult.
Then there’s the content of your message … do you have a distinct writing
style that could be traced back to you? For example, do you have a consistent
set of words that you regularly misspell? (I know I do.) Do you make statements
that only you would know? As we saw some time ago, individuals were able to be
identified only by the Google searches they did over a period of time. Email
can be much more specific and identifiable.
Ultimately, there really is no such thing as “perfect anonymity” on the
internet. You can make it very, very hard and expensive to be identified, but
it’s rarely truly impossible. The best you can hope for is “impractical”. And
just what impractical means depends on what you’re saying, who’d want to know
who you are, and how many resources they can throw at the problem.
Important: I cannot trace email. I cannot trace IP addresses.
I’ve written several articles on both, referenced below, and they all boil down
to “contact law enforcement”. Comments on this article that boil down to “how
do I trace”, or actually requesting me to trace something, will be deleted.
Sorry, but I get this so often, I don’t want these requests that I can’t act on
to get in the way of otherwise interesting discussions.
The poor man’s way to anonymize is to drive to a neighborhood across town and connect to somebody’s unsecured access point with your laptop. If you’re *really* paranoid, you could even drive to a neighboring city or state.
Depending on many things, the email sent from your laptop could still contain information that could be used to identify you, even if using someone else’s internet connection. (Many mailers, for example, include the machine name in the headers of the mail being sent.)
Leo-enjoy your effort to answer questions , that users have. one word aswers this one BLACKBERRY ! MAX
Is the email page a fixed format? I get numerous emails that don’t wrap around and consequently lose a few words at the right edge of the line. I’ve looked for the slide bar at the bottom and some don’t seem to have one. Is there a way to slide the message to the left to read the words. So far the only way I’ve found is to reduce the size of the print by rolling my wheel while holding the control key. The small print is then difficult to read at times. Thanks
It depends entirely on what email program you use, or what web based email service you use. They *should* allow you to scroll right/left, OR they should allow you to automatically wrap text. If they don’t, then I’d consider that a bug of some sort.

I use http://mail.picsent.com and send emails out where people cant tell my email adress but its not for bad! its just cuase i dont want repleys. so i guess leo wouldldnt complain about that!
I prefer to use anonymity services. My favorites are Ultimate Anonymity ( http://www.ultimate-anonymity.com ) and Cotse ( www. cotse.com ). Both offer very cool tools for online anonymity. Ultimate Anonymity offers a secured web based remailer and nifty software you can download to send totally anonymous messages and manipulate the “from” line to be anything you want.
http://www.anonysend.tk lets you send anonymous emails online for free. No sign up required.
We also offer free anonymous web browsing and free anonymous mobile phone text messaging.
Hope that helped!
or you can buy a used cell phone that is capble of going online, get yourself a homeless guy to buy some pre-paid minutes using the name of the person’s wallet he just stole, (make sure it’s not yours) connect online following Leo’s advise above. when finished, get an old rag soaked in bleach, wipe the phone down thoroughly, resell the phone overseas. duh…
that’s how I would Elude…
Excellent article and comments! I am looking for some guidance.
If you were in say a “corporate whistle blower” situation, but with a small (yet very technically savvy company), and the only potential legal infraction could be related to confidentiality, which approach is safest? Oh-and they will not receive email directly-most likely will be forwarded to them from recipient.
1) Drive to different location and connect w/ unsecured wireless
2) Online anonymity services above
Thanks
I just need some clarification. I am going through a situation dealing with a ex who says he got an email through facebook from a friend of mine (the email was not very nice, to say the least) and my friend says it did not come from him. I am just wondering if there is any way to figure out where the email came from on facebook so I can end this.

I was thinking something like this: take my laptop to a neighboring city, connect to an unsecure network, create a fake free email address, create a fake Facebook account then send the email to the person through Facebook. Is there anyway possible, even for a very tech savvy person, to trace the email back to me? I see that the last question (and your answer) dealt with Facebook, but I was unclear as to the path of the email the writer was referring to; it seemed that the email referred to did not take a direct route to the writer (?). My email will go from my fake Facebook acct directly to the Facebook account of the intended. Thanks for your response.
You must try http://www.secure-anonymous-email.com
You can use http://sendanonymemail.info for free, no logging, no captcha.
I have a varaince on the last question and really different situation.
I’m in a whistleblower position, nothing illegal period, but have a good amount of concern for the rain of crap my family and I would have to endure if I were outted. Very paraniod, so much so that writing this is killing me … surely they could trace this too!
So here’s what I was thinking, home, out of the question! library computer, nope you gotta log in at the desk with your library card … but they do have free wifi as does mcdonalds … could I potentially use a free wifi service such as mcdonalds to make a new email address (yahoo etc) and send an email or would something like my mac address remain the same and be tracable back to me?
Additional details … I have a windows vista based laptop, a windows 7 laptop and an IPad I know in the past different windows versions gave different security levels but I know nothing about the IPad. I was bought strictly for fun, we know nothing about macs or mac based products.
Also what if i logged in at mcdonalds to my computer then went to the annomizer then made the email etc … wouldn’t someone be able to trace it back to mcdonalds then potentially back to me because I logged into mcdonalds wifi? Have I now reached too paranoid? Holy freakin cow my mind is now whirling!!!!
Please think about it, let me know! I need to send this soon and I just keep freaking out about getting outted, I have to live here and so do my kids …
Thank you very much!!

Hi Leo
Thanks for the article. Also in the same boat as the last post. I want to know how it will work if you create a free account with Gmail for example, while you are using Firefox’s private browsing. Will your IP still be recorded? Thanks
30-Aug-2011
Hi Leo
Thanks for the feedback. Just an update if anyone else still want to do this. I went to anonymizer.com and they showed my IP and my location. That was with Firefox. Then I went on to Firefox’s – Tools- Start Private browsing, and went to the above site again- again it showed my ip and location, which confirms what you are saying in the above. I then found hidemyass.com, and went on Web Proxy, which opens a banner on top of your Google page for example. Every time I went on Anonymizer through HMA it changed my location and IP- USA, Netherlands, UK, China, Russia etc. If I create a free account through this method with phony details and send my mail via HMA, it surely must be fireproof, or am I missing something? Thanks for the Speedy reply and blessings

Go to the damn library. Yes there may be cameras but I highly doubt there’s one near ur comp. I still haven’t seen a lib with one. Govt is cheap. Wear a hoodie. Fake everything on a Yahoo account. At my lib u don’t have to show card u just write ur name. Say ur abdulhossein abukheider. If ur in ny for ex where u need to show card say u just moved from out of state and don’t have state Id. Librarians are not FBI agents.
Yea. Not 2 many libraries have cams directed at the comps. So what if u were spotted there that doesn’t mean u used comps. and if u do the thing about moving out of state, they issue u a temporary barcode computer pass. don’t ask 4 ur id or nothin. be nice to librarian. fake yahoo account fake everything blah blah. unless ur in a rich town trust me there’s no camera’s anywhere in sight. you can write anything u want won’t say any details but jus trust me. 15+ yrs experien

Hi! I have a paranoid ex husband who uses a tacking system to track down when and where I open his emails etc etc. There was domestic violence in the past and I am going through a difficult time. My question is, how can I ‘confuse’ the tracking system called ‘readverify’ that he is using and not be traced? Thank you.
31-Oct-2011
What about if you send an email from an iPhone, is it still traceable…?
Hi Leo:
I got a new laptop as a gift but haven’t yet opened it. Let’s say I create a computer login like “Jon Doe” on this laptop and use public wifi. Other than “computer name” as you have earlier mentioned, is any other info about my equipment decipherable in an email (MAC address, serial number, etc)?
(By “computer name,” do you mean a user login that is set by the user? Or do you mean some other info that is unique to that computer, as set by the manufacturer?
Thanks.

If I use an anonymous email service, where does it show the email coming from? I’d rather use a fake account such as Yahoo, but I want the email to be sent at a certain set time so I have an “alibi”, and I’ve read you are able to do that with an anonymous site, but I’m not sure with yahoo or gmail, etc.

Hello… I got an email from someone who sent me a link to a craigslist post.
They used a fake email in the “from” section… so it appears to be from someone that I know. However I know for a fact that it was not sent by that person.
Can I trace an email like that? Or is it untraceable because it was sent through Craigslist?

how to send email in an organization to all staff without knowing their Email Id
19-Jan-2012
I am an American who has a friend in I##n. Our emails for 10 years have been neutral, but lately the domestic problems are frustrating him so badly that he wrote two emails about it. I responded to e first with a copy of an article – he never received it, but did receive subsequent emails. Today he emailed me about inflation and other problems. I sanned the email on my phone. When I went back to read it, it was GONE – from my in box, from trash, from my Web email. GONE. The network folks at work guessed that “someone” deleted it from the cloud, which might be in his country.
I write neutral emails to him, but, since I am educating his daughter, sometimes I need specific information. What is the best anonymizer to use? I will also see if he can get to it.
I am worried about him, and, of I go to visit, to meet his family, I am worried about me.
Am I paranoid? Absolutely. Can you help?
Thanks.
If you just want to send a quick and easy anonymous email you can use a site like silentsender.com, no software to download and no hacks.
One smiple word: Tor
