I am getting my share of emails from those wanting to sell me a product or service. Is there a way to stop it? If I click on unsubscribe, it seems I get more of these solicitations. I certainly would like to know who is responsible for giving out my email address.
If it's unsolicited spam you should not click the unsubscribe button. That, as you found out, will generally result in more spam. Log into your email provider and just add the addresses as junk and they should be blocked.
