From work experience, only a small amount of website contact information work to actually contact the person in charge of the website.
My very rough estimated would put it more like:
40% of email addresses is no longer valid or has an mail box that does not get read.
30% reaches the web design shop which built the website many years ago under a different brand. They blindly forward it to their customer if they still have that information. The contact information is many years old and likely a dead end.
20% has auto-reply and do not get read.
1-2% has algorithmic reply that links to a FAQ.
5% actually reach a human being. Those 5% however are still a good enough reason to not do this!
