What is PHPlist PHPlist is a set of PHP pages that implement a simple mailinglist system. It uses Mysql for storing the information. It is designed to be able to deal with a very large amount of email addresses.
Users can sign up to multiple lists.
If a message is sent to multiple lists, they will only receive one copy of the email and not as many as the number of lists they are subscribed to. If people sign up, they can identify the geographical location they're in and when sending an email you can determine which locations need to receive the message. To use PHPlist you need a webserver which supports PHP , a Mysql database and possibly Perl with the Mysql modules installed. Demonstration Check out the demonstration on this site. I'm sorry to say for Non UK users that the current settings are rather UK biased.
