What the experts say5Expert opinions
Expert from Email Geeks explains that sending mail to public contact addresses for advertising purposes, even if 'foraged' from public websites, can be considered spam. These addresses are intended for potential customers to contact the companies, not for unsolicited advertising.
Expert from Email Geeks explains that some filters, like Cloudmark, use user reports to make blocking decisions.

If the sending domain is the same as other mail from the organization it will cause delivery problems for other mail as well as the spam.
