“Dear McAfee Customer,

Don’t miss this important opportunity to help us serve you better. To provide you with the best possible products and services, we need your feedback. You were recently asked to complete a McAfee Customer Satisfaction Survey. If you have already taken the survey, thank you for your participation, no other feedback is necessary. If you have not taken the survey, please take a few minutes to do so now…”

Their product worked so well, I found their email in my spam filter!! So how will they measure the effectiveness of their survey, customer satisfaction or their spam filter? If they have 100% no response - their product is perfect?
