Email Marketing Help

I am trying to do a mass email marketing campaign, and need about 80,000 email sent out a month. I have all the email address, and the fliers that I would like to be placed in the body of the email (not as an attachment). I would like 20,000 emails sent out per week, so 80,000 total for the month. It is a very quick job, when I have done it myself it took no more than 5 minutes a day, the problem I am running into is that all of my emails are going into spam. I provide the email addresses and fliers. If you know a way around this problem and can help me with this job please send me a message. I would like to find someone who can continue to do this more me on a monthly basis, as I have over a million email addresses, so please bid as amount per month for 80,000 emails. Thank you!
