Animus Mailing List
This script allows you to create mailing lists that your customers can opt in to. Additionally, when you send out something to your mailing list you have the option of archiving it -- meaning that people who aren't on your mailing list can see what you sent. Keeping in touch with your customers is key to keeping them your customers, and this script helps you do just that. Whether you intend to use it to inform your customers of upcoming events or just to entertain people, this script should be perfectly suited for your needs. The script is also designed to be painfully simple to operate, you don't even need to know HTML to get it working! It's free to install with links back to my site, so why not give it a shot?
