Gutuma was born out of the need for free mailing list / newsletter software that is geared, not towards mass-marketing companies and spammers, but web developers who need a system that can be easily integrated with an existing web site. It's very easy to install and use, and doesn't even require a database, but it still has lots of powerful features. Internally, Gutuma uses the tried and tested Swift mailer for sending messages, and the SACK library for AJAX subscribe requests.
