SageMailer is a great service and
amazon feedback manager. I use it myself and always recommend it to other sellers on Amazon. It helps Amazon sellers track, manage, and most importantly, improve their seller ratings. Also importantly, SageMailer automatically sends polite requests to your customers to provide product reviews and reviews on your behalf. There are even special pre-built templates for this that are 100% compliant with Amazon's Terms of Service. That's cool!
