Summary: While there are settings and services that claim to be able to determine if email has been opened, they are notoriously unreliable and pointless.

I sent an email to a friend and he claims never to have gotten
it. I don't believe him; things he's said lead me to believe that he did get
it, and that he did read it. Is there a way I can tell for
sure?
|
I'm actually fairly amazed at the number of times that I get questions that boil down to people just not trusting each other. Not that there isn't cause, I suppose, with spam, phishing and viruses running all over the place. But this seems like the simplest case of all - was your email read or not?
Interestingly enough there is infrastructure in the mail system to get an answer to that question. The problem is that, for all practical purposes, it doesn't work.

I'll give you the quick answer first: no, I don't know of any way to reliably determine if your email has been delivered, and if it was delivered whether it was opened, and if it was opened, whether or not it was read.
I can hear a lot of you asking "but what about the delivery confirmation option in my mail client?" That's the "infrastructure" I talked about earlier. The problem is that 99% of the time, it simply doesn't work.
Delivery Confirmation is nothing more than an additional header added to your outgoing email that asks the recipient's email client "please email me back when this is delivered to the inbox". Note that it requires the cooperation of the recipients email client - they have to a) recognize that request for confirmation, and then b) do something about it.
Most email clients ignore Delivery Confirmation on incoming mail.
Why? Either the email client simply doesn't support the feature, or (more commonly) the user has turned it off for privacy reasons. I know I do.
The same is true for Read Receipt - it asks the recipient's email client "please email me when this message has been opened". Again, if their email client supports it, most people turn this off for privacy reasons.
Now there is one common trick that some folks, mostly email marketers, use to see if email has been opened. Using HTML mail, they can reference a picture from a remote server. For example, I can create an HTML email that includes a picture of my dog, but have that picture reside on my server. Then, when you open the mail, the picture of my dog is fetched from the server, and I can use my server logs to see that.
The problem here is that because this feature has been so misused by spammers and the like, most email clients now don't display those images unless explicitly asked to by the person reading the email. If those pictures aren't displayed, the server isn't notified, and there's no way to tell that the email was opened.
So, so far all our techniques for testing to see if email was delivered or opened are failing most of the time. There's simply no way reliably tell if an email has been delivered or opened.
But, let's say for a moment there was. Let's say we could tell that email was delivered and opened. Even with that - how could you possibly tell that a person actually read it? You can't. Even if the person has it open on their computer there's no way to tell that they're actually reading it.

Can I track the IP address of the email sender?
Posted by: Shingenge at February 22, 2007 11:20 AMOn the same topic, does an auto response (on vacation) from recipiant of my email actually mean that they did indeed get my email, or could it have gone into their spam/bulk folder and not have been seen?

There's no way to know. I'd expect it means it got delivered, BUT:
- - that's an assumption and could easily be wrong. It might not be true for all
mail systems and mail programs
- - there's still no guarantee that on returning from vacation or whatever the
recipient actually found, opened and read the mail.

Posted by: rincy at June 23, 2007 2:52 AMHas anyone tried www.spypig.com? It's a free email tracking service. How good and reliable is it? Is it safe to use?

Short answer: all email tracking services are unreliable. Longer answer:

Seems Leo doesn't know too much. It's simple. Just go to Msgtag.com & download their free software. It works if you fall in the categories that they say it will work in. Very nifty program - I use it & it works great.
Posted by: Boo at November 19, 2007 1:34 AMThere's another way to tell if your email has been read. Through spypig you can tell if your email has been read. the process has been detailed at techbanyan here

As I keep saying again and again these techniques all rely
on images being viewed by your recipient. If the recipient
does not view images then there is *no way* to determine
whether they've opened your email. Period.
I'm closing comments on this article because too many people
keep posting false and misleading information.
