Seems quite useful. Though I was wondering;

How do you measure the "relation" one has with a user? I.e. going from red to green on the meter - what are the factors?

Does your service also provide, built-in, the ability for our users to give us feedback directly at our own site?

Lastly, if you can, would you mind sharing with us the name of the 3rd party service you're referring to (to find social data from email addresses)?

Anyways, something like this might very well be what we've been looking for. Or rather, we're looking for a method/service/platform to enable us to effectivly communicate with our customers (not necesserily in terms of "effective medium").
