Anonymous email

Long-term anonymous email accounts

Sometimes you just want a truly anonymous email account. Spammers already know how to do this -- why shouldn't you? The information below is largely from this Global Voices Online article.

  • With Tor running and your Torbutton on or with Tor enabled as a proxy (I assume you're running Firefox with Noscript for blocking scripts), access the Mail2Tor hidden service at http://mail2tor2zyjdctd.onion (or the MailTor hidden service at http://mailtoralnhyol5v.onion ). (Alternatively, with Tor running and your Torbutton turned on or with Tor enabled as a proxy, find a similar service listed on this hidden service wiki: http://kpvz7ki2v5agwt35.onion/wiki/index.php/Email .) Create a free email account there. This account will be used only as your "verification email" account.
  • had a very good free email service that was similar (and also worked with Tor) until it was shut down in August 2013 while refusing to supply copies of private email to the US government / NSA. As a result this provider recommends only using (reliable) anonymous email services outside the borders of the USA. Also read this article from the Stanford University Law School Center for Internet and Society.
  • Hush Mail has a free web-based email account with 25 Mb storage, if you are willing to sign in at least every 3 weeks.
  • With Tor running and your Torbutton on on or with Tor enabled as a proxy (I assume you're running Firefox and Noscript is blocking scripts), access the AIM Mail web-based email service. Sign up for a free email account there, using the previously established Mail2Tor account as your verification email address.
  • Current password crackers (such as John the Ripper) can run through millions of passwords in a few hours (see this H-open article). A random password can be generated using a random password generator and used for your email password. Such passwords can be used for "secret questions" if those are required by the email service, as well. (An anonymous user suggests that even the usernames for the "verification" email accounts can consist of a randomly generated set of characters -- good idea!)
  • It is relatively insecure to allow one email account to send passwords or password-reset links to a "verification" email account (such as the one set up at Mail2Tor). If the "verification" email account were to become compromised, it would be trivial for the hacker to reset the password at the main email account which uses it for verification. Furthermore, it is difficult to know who is running an email server in the first place, and it is wise to assume that the email on an email server (such as Mail2Tor) can be examined by the owners of the email server. Of course, that's why you're using email through Tor in the first place -- for deniability in case the email server is compromised (and your email is intercepted).
  • A solution is to daisy-chain the verification email accounts. In such a scenario, the Mail2Tor account is set up first. Then (for example) a 60-day free Fastmail is set up using the Mail2Tor account for verification. Once a Fastmail email account is set up, the Fastmail email account is then used as the verification email for the AIM Mail account.
  • Any or all of the "verification" email accounts (such as the original Mail2Tor account) can then be deleted, leaving only the AIM Mail account (and optionally the Fastmail account) remaining. It should be noted that Mail2Tor, Fastmail, and AIM Mail are all in different countries, which lends an added level of security.

Always use email through the Tor network or risk exposing your IP address(es). Always use an encrypted (https) connection as well, or risk exposing your data to a rogue Tor node. (All sensitive email should be encrypted using PGP, of course, and never sent in cleartext.)

  • AIM Mail and Fastmail are robust, high-bandwidth mail servers (unlike Mail2Tor) and are Tor-transparent (unlike Yahoo Mail and other free email services), nor do they have the high level of tracking mechanisms that GMail has. They also allow IMAP and SMTP through Tor (in case you desire to use them in that way).
  • There are other Tor-permissive email services, however (including Want a review of the compatibility of other (free) email services with Tor? Then see this hidden service wiki (with Tor running and your Torbutton turned on or with Tor enabled as a proxy): http://kpvz7ki2v5agwt35.onion/wiki/index.php/Email
  • You could use the Mail2Tor (and/or Fastmail) account as your verification email account for a variety of services and if those services were available through Tor as well, you could be anonymous with them, too! However, once you use the Mail2Tor (and/or Fastmail) account for anything other than a verification email account, the chances of cross-correlation go up. I therefore recommend reserving a single Mail2Tor (and/or Fastmail) account for that purpose (i.e. as a verification account) only.
  • Here are some moderated lists of other Tor hidden services from the Deep Web Wiki (primarily accessible with Tor running and your Torbutton turned on or with Tor enabled as a proxy):


BitMessage is a Python (script), encrypted, peer-to-peer messaging system. Some advocates tout this as the most secure email protocol (see the Wikipedia article). Installation instructions are here. Usage help is here.

  • Install dependencies (some may already be installed on your system):
sudo apt-get install python openssl git python-qt4
  • Download the source code from github:
git clone $HOME/PyBitmessage
  • Run PyBitmessage:
  • If you receive a warning that you need to use python 2.7.5 or greater, and have followed the above instructions to upgrade it, your system may be attemping to run PyBitmessage with python 3. In this case, run:
python2 ~/PyBitmessage/src/
  • To upgrade Bitmessage run the following commands:
cd $HOME/PyBitmessage 
git pull

Temporary non-anonymous email accounts

  • Sometimes you just need a temporary email account just to sign up for some commenting system or something. Perhaps they send a "click this link to verify account" email, which is all you really need. Such emails need not be secure or private, since passwords and other identifying information is usually not sent in such messages.
  • Mailinator is the ideal solution for this type of temporary email account. It does not allow sending emails (and therefore is not apporpriate if you are trying to be a spammer), but it does allow you to receive one-time emails. You could use such an email account to receive a one-time message from some website (a coupon or something like that) which you know will generate endless spam in the future. With the temporary email account, you can "Let them eat spam!"
  • A random string of characters can be generated using a random password generator and used as your email username. Mailinator allows a user ID up to 25 characters. (Mailinator can provide a random userID, as well.)
  • This is a great service, and the guy who runs it is very well-educated and amusing. Note that there is no privacy whatsoever with this service, except in the obscurity of your chosen email name. All messages to the temporary email box are deleted within a day.
  • Uh, yeah, of course you should access Mailinator through Tor, unless you particularly want your IP address to be identified with the temporary email account. The guy from Mailinator says he gets subpoena requests all the time. Stay protected. Use Tor when accessing Mailinator. IMPORTANT UPDATE: Mailinator is no longer accessible through Tor. Without a trusted proxy (and how many VPN proxies are actually trustworthy?), access to Mailinator must be assumed to be insecure and monitored. NEVER use it for emails you don't want tracked to your IP address.
  • Spamgourmet is another service that allows temporary, discardable email addresses. It allows forwarding of up to three messages to another email account (perhaps your longterm anonymous email account?) so that you can give a Spamgourmet email address to some website, have their reply forwarded to your regular email account, and then not worry about the subsequent spam (after the first 3 messages) that inevitably follows. Spamgourmet discards anything after the first 3 messages.

Anonymous blogging

  • Now that you have an anonymous email account, why not set up an anonymous blog? I mean, are you any less reliable than a paid "journalist" that posts their poorly written nonsense on online newspapers? Here are some sites that allow anonymous blogs:
  • allows free blogs.
  • Wordpress allows free blogs, but has a number of censorship rules and tends to remove sites quite quickly based on any complaint whatsoever. Here is a list of other hosts that allow free blogs using the Wordpress blogging software.
  • was bought by Google and is available with a Google account. Anything hosted by Google must be assumed to be insecure, but for limited uses it may fit your needs.
  • Here is a 2007 list of other free blog sites. I'm not sure how many are still functional.
  • There have been several high-profile lawsuits of anonymous bloggers being sued after being tracked through their IP address using Java-based scripts or by Google Analytics. You are using NoScript to block Google Analytics and Java scripts, aren't you? Of course, I KNOW you are accessing your blog only through Tor... right? See the Global Voices Online article regarding anonymous blogging (with Tor).

Other considerations

  • Traditonal forensics have always used the evaluation of writing styles to identify authors. See this article. Frequent posts from the same author allow evaluation of writing patterns. One way to get around this is to use a translation service. Translate a message into another language, then translate the result back into the original language. This introduces random errors, making the writing style less consistently recognisable. (Be careful to use Tor when using Google Translate or other online services, of course, since Google and others use extensive tracking mechanisms.) Another useful tool is FauxCrypt. Finally, Anonymouth is a Java-based project for anonymizing writing styles (also see here).

Using an SMTP server

  • You can easily send anonymous emails with your own SMTP server. This is how spammers and other malevolent Internet users accomplish it. See this article for an example. (Spammers suck, though. Heck, beating spam is the purpose of much of this page, isn't it? Why contribute to it?)
  • Read the Tor instructions for setting up a hidden service.
