Nicereply wants to help you improve the emails you send to your customers:

Now, I generally try to focus on consumer web sites here on Venture Pimp, but Nicereply is too good of an idea to pass by. The idea is that you, writing emails for your company, add a unique link to your emails that prompts recipients to rate the message. They click that link and are able to rate your email (1-5 stars) and add a personal comment.

The interface is quick and attractive, and there’s a pretty thorough API available for accessing all of your data. There’s a live demo for you to play with the administration interface and get a feel for how the system works. It feels very solid.

Feedback is very important, and this seems like a way to lower the barrier to entry for end-users. In the future, I can see this expand to offer some sort of reward for sending feedback, but it’s already a great idea.
