Dada Mail
Dada Mail is a completely contemporary, mature and intuitive web-based e-mail list management system, which runs on most any Unix-like hosting account that can run custom CGI scripts.
Dada Mail handles Closed-Loop Opt-in/Opt-out subscriptions, sending complex announce-only and/or discussion mailing list messages with an advanced, fault-tolerant mass mailing monitor, supports the archiving/viewing/searching/resending/syndicating (rss, atom feeds) of sent messages and doing all this and a whole lot more with style.
Dada Mail can handle custom subscriber fields and you can use the information it captures for partial list sending based on a query and Dada Mail's email templating system allows you to create targeted and completely custom email messages for each and every one one of your subscribers.
Dada Mail is bundled with additional plugins and extensions to extend Dada Mail's capabilities. Some of the plugins/extensions support advanced bounce handling, clickthrough tracking, mass mail scheduling, blog interfaces of archived messages, AJAX subscription form trickery and lots of other surprises.
Dada Mail produces XHTML valid web content and sticks to best practices when creating email messages. Write Once: Distribute Everywhere. Dada Mail is free software that you're able to use, modify, share and enhance under the terms of the GNU General Public License. Dada Mail is written in Perl because we love Perl.
