We have all heard and read about the privacy issues when it comes to Facebook, Yahoo, Google, etc. and your email is included in that. Data is kept to allow tracking of your habits in order to show the most relevant ads to you.
Most of us have gotten used to this and are okay with it but a person may rather have an email account that is private and not being used for advertising. Many people are now getting away from that.
If you would like a private email account, even without a website, contact me for more information.
