Dada Mail v8.4.0 was recently released (hurray!) One of the ways I've been experimenting with showing people all the cool features of Dada Mail is by doing screencasts - below are some of the screencasts I've recently put together.
Dada Mail v8 Quick Install Guide:
This screencast is meant to showcase just how easy it is to install Dada Mail, using the web-based installer. Dada Mail does have a CLI installer, as well - that's the way to go, if you want to automate an install/upgrade, as well as to take advantage of Dada Mail's PSGI/Plack support.
Importing Addresses into Dada Mail:
Many people using Dada Mail - especially for discussion lists, are moving from a previous system (like Mailman) - this screencast was created to show how easy it is to import an already-created list over.
Magic User Templates
This screencast shows how to change the layout of Dada Mail to match your own website - it using HTML::Tree under the hood, which I wrote about, recently.
Dada Mail Scheduled Mailings:
This screencast showcases a few mature features in Dada Mail, including Sending a Webpage (whole or in part), as well as setting up a recurring scheduled mass mailing, that only sends when the source content has changed. Neat stuff.
Give Dada Mail a spin, if you haven't already - it's a long running, and fairly popular Perl web app. I would say one of the most popular Perl-based web app targeted for regular folks (as opposed to Perl hackers)
