What is the purpose and how
do I make use of codes and scripts like PHP, Java, CGI, Perl, etc.?
Scripts and codes
is a popular method used by many emailers to embed it into their formatted
HTML emails--usually without the recipients consent--to track and gather
information.
Javascript
is code that is written as text within the HTML source of the web page and is
often used to check the data entered into a webpage form, then the visitor's
web browser interprets and executes the code rather than a web server.
Check it out, some free javascripts with easy
installation instructions and lots of cool stuff, there's even a tutorial on
how to write it;

PHP is a
powerful scripting language adopted in commercial websites. PHP (an
alternative to Perl and the cgi-bin) is easy even for non-coders and can be
easily integrated into HTML pages (just like Javascript).

Perl (Practical
Extraction and Report Language): The most common scripting language for
processing Form data.

How to embed your HTML email with tracker code?
CGI (Common
Gateway Interface): A protocol for gathering data from a Form and sending it
to a program or Script such as
Perl (a transfer interface) method for
processing a Form.
You use CGI scripts when you want 2-way communication with
your readers.
For a simple quick
non-technical layperson over-view
about CGI
CGI scripts are often written
in the following languages:
Perl, C/C++, Visual Basic - Scripts written in
the above languages are called server-side scripts as they are located on the
server and are executed only when a user clicks 'submit' on a fill-out form.
And JavaScript, VBScript - are known as
client-side scripting languages and are located in HTML documents and are
executed by your browser.
