Email Rotator that sends single emails each time

I know there are email services that are less stringent that can allow easily switching between accounts. Is it possible to make a bot that switches between these emails and sends one single email each time? I know this would be quite complicated but I've found sending a single email from one email account and then switching has had better results for me than bulk sending. Worst comes to worst, I could get a virtual assistant to go through and send the emails as well. But I'm just looking for the easiest way.

how many emails u wanna send? i have solutions for you through smtp and bulk emailing software.

I've done lots of smtp and bulk software. Still not as effective as sending an individual email, which has much higher deliverability. If a bot like that existed, it would be awesome. I just want to send 1000 a day.
