Definition
Reply rate is emails replied divided by emails delivered. A healthy cold email campaign runs at 3 to 8 percent total reply rate.
Why it matters
Reply rate is the strongest early signal on ICP fit and copy quality. Below 1 percent means your list, copy, or deliverability is broken.
How it works
- Measure per campaign, per list, per persona
- Split total reply rate from positive reply rate
- A B test subject lines and opening lines to improve
