Dear heri,
It is quite simple:
Either you can choose
cgi.resourceindex.com/Programs_and_Scripts/Perl/Mailing_Lists/
Or
chipmunk-scripts.com/page.php?ID=12
Or
yourmailinglistprovider.com/
Or
mojo.skazat.com/
Even you can read
plus2net.com/articles/php_newsletter_script.php too.
I wont be able to post the links so I just made them blue. Hope this will help you. Do let us know which one you have implemented..
Cheers
