Get alerts when the emails you send are opened

Inspired by spypig.com, a site that helps you track when your emails are opened, I decided to see if I could write a script with the same functionality. It tuned out to be a rather interesting project.

Here it is: http://www.classicalcode.com/t.php

It works by generating an image which you embed in your email. Then when your recipeint reads their email, their email client downloads that image. Downloading that image triggers a script on my server which then sends you an email.

In order to make the image look less suspicious I implemented a feature where the image is a string of text of the senders choosing. Example:

An Example of a tracker image from my email tracking project

Give it a try!

    This sounds like an excellent script, however when I open the pages I get this error:
    Warning: require(/usr/share/php/class.phpmailer.php) [function.require]: failed to open stream: No such file or directory in /var/www/t.php on line 73

    Fatal error: require() [function.require]: Failed opening required ‘/usr/share/php/class.phpmailer.php’ (include_path=’.:/usr/share/php5′) in /var/www/t.php on line 73
