Some people do not like to send their offerings to a web-based email address. They prefer the "comfort" of thinking that the organisation can "afford" a private email address associated directly and uniquely with the name of the product.
If it were as you suggest then why would the national papers bother with their own email addresses?
You are not dealing with an amateur here
Meanwhile the email address for those wishing to contact me that is displayed in my profile on this forum is web-based (google mail) but still hides my name.
Personal emails in my name can reach me via Yahoo mail but that is reserved for family.
As a back-up and should all else fail there is another via hotmail
