Half of the "tested" outbound I read was decided on 50 sends — enough to check delivery and copy mechanics, never enough to read an offer: reply-rate needs ~1,500–2,000 sends per variant, and subject/open reads need 100–500 per variant. Below those numbers, easy and ordinary are indistinguishable, so the variant that wins the coin flip gets the budget and the one that actually works gets killed. Write down what your volume cannot answer before you act on it — that single habit saves more than any tool. Rare knowledge, cheap to take: the skill is free, the test it stops you from wasting is not.
