hey there
i have read and understood your project requirements, i can install and configure nulled mailwizz to server the purpose of bulk emailing. I have done MCS and i am expert with setting up email servers. if you want to send bulk emails, it can be served with a single IP if you have the genuine opt in list and you dont need to purchase extra IPs.
Kindly message me for further details.
Cheers :)
