Track message opens/read

[vivek avasthi]

i want to send mail to users from my site , and then track open/read of that messages . like my site is sitename.com and i send mail on [e-mail] ...is it possibel to track message

[jatar_k]

you can track them by using a bug

this is normally an image, transparent 1x1 often, or even an img tag that targets a php script and passes a param to know what email it is

though I guess 1x1 images would probably get a spam flag these days

Yes, your email is more likely to be flagged as spam if you have some tracking code in it. Additionally, many people now read email with HTML and/or images turned off for this very reason.

Question:
Will the PHP param be considered as spam?
and if OK what would/could be the scritp logic?
Thanks

Yes, it would be considered as spam if it can b recognised as a way to track visitors.

You could add an "image" like this:

<img src="http://www.example.com/script.php?var1=xyz&var2=xyz" height="0" width="0" />

And then the script can make use of the variables in the usual way.
