Contacting customers via Email is a very efficient way to notify customers of items that they need to know. However, Email can be misused easily and can infringe on the privacy of individuals who have given you their Email addresses.

There is a difference in how to treat this issue as a P3P policy element, and how to treat this issue as an infringement on privacy. We hope to discuss both adequately so you can understand how to use Email as a tool for customer service as well as marketing.

When the privacy policy declares elements showing the site will contact the user, there can be P3P implications for cookies such as having them downgraded or blocked. As a website owner, it is good to know when site functionality will be affected.

The decision to use email to market products carries some responsibilities to allow users to unsubscribe as well as being truthful about who is sending the email and why is it being sent.
