Can a brand-new sending address just start blasting your whole list?

Can a brand-new sending address just start blasting your whole list?

Got a fresh email tool or domain? It's tempting to email all 5,000 people on day one. But a new sender has zero reputation, and a sudden flood looks exactly like a spammer, which is why it matters. Inbox providers throttle or junk you fast.

Do a gentle "warm-up" instead:
— Start small: email your most engaged few hundred subscribers first.
✅ Increase your daily volume gradually over 2 to 4 weeks, watching that opens stay healthy.
— Only add the quieter, older contacts once your reputation is solid.

Think of it like merging onto a highway: speed up gradually, don't slam the gas.

Tiny homework: pick the 100 subscribers who open you most. They're your warm-up crew.
