Have a current site with comments added. Is it permissable to email the list of those users who have commented with emails since they added a comment for the site? Want to promote some affiliate related stuff and annoucements but wasn't sure if that is considered ok or not. I'm assuming i'd have to go through the comments and copy/paste the email addresses versus a wordpress related extractor for it right? any comments welcome.
Not a chance! Email details on comments should only be used directly for info related to the post i.e. someone else has made a comment. Do not spam your readers with unwanted affiliate crap. Create a newsletter submission form and if anyone signs up then send them the info.
