I need email servers that allow me to send email messages to a list of subscribers. I need to send around 5,000 emails per month. I have everything I need except the servers. I already have my opt-in database of email addresses, software to send the messages, etc. I need to point my software program to mail servers that allow me to get the messages out. The messages have to reach the inbox and not go to the SPAM box. Therefore, I need multiple servers that I can rotate (or some other mechanism that assures my messages will get into the inbox). I am willing to pay on a monthly basis for this service. Therefore, your quote should be the monthly fee you will charge to provide this service.
