Hi, I´m a little surprised that no one posted here about Zookoda, so I decided to write a little review about it. Is a free service that provide you a simple way to put a input box on your website/blog that allow users to subscribe to a email list. You can create many mailing lists as you wish. You can also custumize the layout of the email or use one from thhe templates. And the best part, IMHO, it has a feature that automatically broadcast the email for you, using your blog RSS as feed.... There are a lot of others features, check yourself Zookoda If you still unsure about using Newsletters, you should check Jakob Nielsens´s alertbox about Email Newsletter: Email Newsletters Pick Up Where Websites Leave Off I hope that this service helps you as it is helping me...
