Why "just send more" eventually sends nothing

Why "just send more" eventually sends nothing

Everyone says: "Outreach is a numbers game — crank the volume and the deals follow."

Myth. Volume isn't free; it's borrowed against your domain reputation. Past a threshold, spam filters throttle you, opens crater, and the same 300 sends that worked last month now reach 40 inboxes. The numbers game has a denominator nobody mentions: deliverability. Craft isn't the soft alternative to scale — it's what lets you scale at all, because relevant mail gets marked "not spam" and bad mail gets your domain quietly shadow-binned. You don't run out of prospects. You run out of inbox.
