I have installed the component recently and I can say that it is exactly what I needed. You can create lists with users and you can send newsletters to one or many lists. Adding of the users is not as simple as possible, but you can get it for 20 min. One proposal - if component allows to be included an unsubscribe link in the newsletter mail will be good feature for the admins and users. Thank you for the great component.
Thank you for your review.
You can easily include an unsubscribe link in your Newsletter.
Please click on the button "tags" when you edit your Newsletter and you will access a series of tags such as the unsubscribe link, the "modify your subscription" link and the possibility to insert many other information (Joomla articles, twitter/facebook/linkedin share icons, user's name...)
