Most people running cold email are stuck in the same loop. They buy domains, set up mailboxes, send a few campaigns, and watch their emails disappear into spam. Reply rates tank, clients churn, and they have no idea what actually went wrong. The frustrating part is that none of the tools they pay for tell them why.
This masterclass walks you through the exact deliverability system used to send over 2.3 million cold emails and generate $1.7 million in sales in 2025. You’ll learn how ESPs like Google and Microsoft actually work behind the scenes, how spam filters decide where your emails land, and what changed in 2024 that made cold email deliverability harder than ever. You’ll see exactly how to buy and configure domains on Spaceship, set up Google or Microsoft mailboxes through Zapmail, and structure your sending volume across primary and secondary domains the right way.
By the end you’ll have a full cold email infrastructure ready to go. You’ll know exactly how many domains and mailboxes to buy for your daily volume, you’ll have a properly configured sequencer in Instantly AI, and you’ll have a complete deliverability checklist to run before launching any campaign. You’ll also understand the math behind why most setups get burned in 2 to 9 months and how to avoid the country-based IP reputation trap that silently destroys deliverability for thousands of cold emailers every day.
