The ease of use and flexibility of the tool makes it easy to get started with. I have been able to create all my campaigns from scratch and also set up mailing lists and segmentation. It's great that you can track results easily using Google Analytics. We are now able to send out emails to our subscribers automatically which has improved customer service. I haven't found anything I dislike about this product so far. I would recommend Zettasphere to anyone who wants to automate their email marketing. We were unable to send out automated emails before we used Zettasphere. Now we do!
