Bulk email

i would like to know where i can send out a mass amount of emails for a certain price that will be spam free but yet allow me to get a huge amount of hits to my website. I know of paidmails.com and i have used them, but i would like to diversify the audience so i am looking for any other places where it is similar in nature to paidmails.com where i can grow in traffic to get better listed in the search engines… AND THAT ARE NOT SCAMS!
im definately focusing on ‘opt-in’ marketing companies like corey mentioned. i do not want to deal with companies that just randomly send emails to random people… i definately know that spamming is bad news… but i dont think optin would get you in a bad situation…

ps. i **** spam too.
