Bulk mailing 100,000-120,000 lowest bid wins

I need someone to inbox 100,000-120,000 emails. Ideally, I need proof that you have inboxed 80%-90% and you must not use send-from emails that look riduculous. Domain emails are fine as long as it looks like it came from a real name. I will know if they are inboxing because many of these have auto-replies because of the nature of the mailing. I will not have a URL in the message but I can provide the copy, randomized if necessary. I need only to collect the responses. I need this project done as soon as possible. I will also need your real contact information. I do partial payment upfront, and then pay in increments until completion. I am doing it this way because at least 4 mailers have taken my money and then lied about the mailing. Thank you!
