Email Tracking

[kingbear]

I apologize if this has already been asked.

I've developed a php based email tracking system in the usual way, i.e. using an <img> tag like <img src="script.php">

I'd like to know how long the email remained open. Can anyone suggest a technique to get this information?

I'm trying to avoid any javascript as it's poorly supported in most email clients.

Thanks for any help.

Hi!

Can you tell me how this works? Does the script.php file actually contain a script or is it just a blank file?

Thanks!
