When I was searching for a newsletter component, most of the extensions I found was either proprietary ones or old components which required legacy mode. After looking at ccNewsletter I was very impressed. It was doing its job very nicely and was very easy to use for my client. One additional advantage of the component is its MVC based code. Thanks to that, I wrote a user plugin and achieved auto-subscription upon registration in 4 lines. Apart from a few untranslated description texts I couldn't find anything bad about it.

Overall, it's a fantastic job. Thanks very much to developers.
