So I've got a problem. I bought an established marketing business with domain and subscribers, but I'm afraid I may get blacklisted across the board because of my volume. I'm sending daily newsletters that I write myself, but I only have 3 IP's (just added the 3rd tonight). I have approximately 480,000 subs that I'm emailing which comes down to an enormous amount per IP. From what I've found in my research, a good range is about 100-300 emails per IP per day. Unfortunately, until my affiliate link kicks in I can't afford the cost associated with the number of IP's I would need to reduce the risk of being blacklisted all over the place. So I have a couple questions I'm hoping someone can help me with. Did I find the correct info about emails/IP/day? Is 100-300 about right, or is the threshold higher? Until I can get a bigger pool of IP's, short of cutting down the number of emails I send is there anything at all that I can do to minimize the risk of being blacklisted? I have my DNS configured correctly, and my emails contain the precedence bulk entry (still doesn't help with gmail LOL), I'm not trying to sell anything within the newsletter, it just contains whatever I have written and my hoplink. I'm following all email formatting best practices that I have found, etc etc etc Please help.
