How can I check if an e-mail was opened?

I'm looking for a reliable way to check if user opened an e-mail which I sent to him. I know I can use some images generated by PHP script (and save client headers / data on server-side), but my question is - is this reliable? Some web clients have disabled images by default, I'm not sure about proxy severs, BlackBerry etc...

So - Is there a good and reliable solutions to this problem?

Thanks.

Solution

  • There is no reliable solution (and I'm glad there isn't). If the user only views your mail as text then nothing (besides the mail itself) gets downloaded or anything like that.
