The Core Question: Does Inbox Placement Matter to You?
MailPilot at 99.2% vs Warmup Inbox at 90% is a 9.2-point difference - 92 fewer emails in the inbox per 1,000 sent. If a reply is worth $500 in pipeline and 1% of replies convert, that's roughly $460 in extra pipeline per send, and MailPilot costs less to run. Inbox placement drives cold-email revenue, and the gap here is real.
