About Me


I'm Mahesh. I study cold email infrastructure and test different sending systems to understand what actually works at scale.

After seeing too many freelancers and agencies burn domains using the wrong tools, I built this resource to explain how to send high volumes safely.

This site breaks down the exact system I recommend.
