I have a great B2B email list of about 75,000 professionals in a service niche (doctors, etc). I can drip blast about 500 people a day promoting a niche service I do for their industry which I want to focus on so I can streamline. At some point, these domains are going to get popped by the spam houses... Should I purchase a few secondary similar named domains and email from those while doing a temporary redirect to my site if they want to visit? Would I be safe from getting my money site domain banned if these blasts are coming from other domain email addresses but the pages are temporarily forwarding to my site so they can find out more information?
