Testing didtheyreadit.com's Mail-Tracking Claims
iosdaemon writes "didtheyreadit.com claims to be able to track your sent email: "When, exactly, your email was opened. How long your email remained opened. Where, geographically, your email was viewed. DidTheyReadIt works with every single internet provider and e-mail account, including EarthLink, AOL, NetZero, Juno, Netscape, Hotmail, Yahoo, and much more." Read on for more.
"This appears to be snake oil. I put it to test just in case someone had come up with some magical code. I sent email from a Yahoo.com account through the service, to an account on a Linux Box. Running tcpdump, I received the email from my pop and let 5 minutes pass before opening it. I left the message open with the cursor in the text for another 5 minutes. Tcpdump revealed absolutely no questionable traffic. And, the service control panel indicated the email had not been viewed. Sending email to a Yahoo.com account results in a 'read' in the service CP. But I had the message open for 10 minutes, and it indicated a 2-minute read......"
The company's "How it works" page explains the system to some degree; it involves redirecting all mail to be tracked through their servers by appending "didtheyreadit.com" to your recipient's email address. I doubt this is mutt-compatible ... Reader xrxzzy points out USAToday's article on the service as well.
Here's a working link: http://www.didtheyreadit.com/.

So not only will it not work in text-based email clients (such as mutt), it won't work in modern versions of Outlook which block inline images by default.
(It was nice enough to leave my plain-old-text message - "blah blah blah" - alone in the original format, as well as adding a text/html mangled version.)
This flies in the face of science.
Well, it will tell you when they opened the email/how many times/etc. (assuming they have an html enabled email client.) It works w/ yahoo mail but not with pine. The infinite refresh to tell how long they read the email for is annoying in that it makes it look like the email never finished loading. Can someone see how outlook responds to this? (I haven't a windows box)

just set your mail client to not download images
Nothing special, just "Webbug" images, which spamfilters such as SpamAssasin (in the default setting) adds point to as more likely to be spam, so using DidTheyReadIt users mail is more likely to end up in a spamfolder than any other type of mail.
On another note, I find it's walking on the thin red line of immoral behavior, and I know here in Denmark there've been several companies who've got bad publicity because of using said method.

The time is probably calculated by not actually sending the image file, or sending it very slowly. So they just keep the HTTP session open, then note when the client closes. That would limit the tracking time to when the connection times out. Like the author said, he left the Yahoo mail open for 10 minutes and it only reported 2.
An additional note, Yahoo does have an option to disable remote images, which would also break this.
Seems this company is too late to the party. Almost all current e-mail clients now don't or have an option to not to load remote images.
Of course, if you use an email program that's that, umm, "open", they could just embed a trojan in it and add features like listening to what you say when you open the mail, and pictures of you reading it. :)
At the bottom of the mail is:
Oh well. Should prove very effective against those without the sense to turn off images anyway. Lets hear it for making money from people's ignorance!

Uhmm... you do understand that Mozilla and other E-mail client do actually have read receipts and that this isn't a "MS" standard?
The only difference in clients abilities with regards to read receipts is how they present you the uninformed user the dialog box saying "Sender has requested you inform them that you have read this message".
http://www.rampellsoft.com/, the people bringing you didtheyreadit looks to me like a really evil company.

Oh, sorry, record, my bad.
By default, Google mail has images turned off. You have to click a link at the top of the message to force it to load the images.
Most other mailers also have a way to turn off image loading because spammers have been using this tracking technique for a long time. If mailers don't allow image blocking yet, I'm sure that a service like this will get them to add that trivial feature.
Not that I let my email client load images anyway, but just because I'm spiteful, I think I'll go add /etc/hosts file. (c:\windows\hosts in win98, C:\windows\system32\drivers\etc\ in XP, )

If you're wanting to use something along these lines, a more up-front company that doesn't use invisible web bugs is HaveTheyReadItYet.
They use images of stamps, which are customizable, which is kind of a cool idea.
However, this only available for Windows.
just put:
127.0.0.1 didtheyreadit.com
In your hosts file...
Or put an authoritative zone in your DNS servers if you have access.
Done, no query reaches their server.
