All of you guys are making fantastic points, I truly appreciate it.
As a IPv4 broker, it's essential to keep the reputation of your addresses clean. A good reputation means less spam filters, higher email rates, and less chance of being entirely blocked. Of course, it's not always easy to keep a perfect score. Why is this? Most IPv4 addresses have been used before and may have a bad reputation as a result of the actions of previous owners. By keeping your addresses clean, you can avoid these problems and ensure that your emails get delivered. It'll pay off in the long run.
