I've used Feedback Genius for almost a year now and I love the service and the guys who created it. I initially started using the service to help improve my seller rating on Amazon. After a few months I noticed that my rating had increased due to more positive feedback left from customers. I like that the service notifies you as soon as someone leaves a negative review so that you can address it right away. I also like that they have statistics to see when most of your emails are opened so that you can make adjustments as to when you send out your customer emails. You can also add attachments to the emails to send customers a free e-book, a bonus, further instructions etc. Overall I highly recommend the Feedback Genius and the customer service is excellent as well.
