I used Jmailer to upload the national list that I purchased and sent my email that way. It was easy to use and I actually copied the HTML from one of my other mass mailers that didn't allow me to send to a "purchased list". The email looked identical and was sent over a period of weeks not all at once. I guess that helps with delivery to "inbox" vs. "junk". It wasn't expensive vs. what the others wanted me to pay to send to 10K+ emails. Here is the link. Hope this helps.
