Positive reply rate
The share of messages that get an interested response — not just any answer. The metric that actually correlates with pipeline, since 'no thanks' is also a reply.
Raw reply rate flatters bad campaigns: provocative or confusing messages generate responses that lead nowhere. Positive reply rate forces the real question — did the right person say 'tell me more'? It requires classifying replies (interested / not now / not a fit / unsubscribe), which is exactly the kind of judgment work an agent does well and a sequencer doesn't do at all.
