“The reply rate you assume can change the workload fivefold.”
Here's the problem. Two big cold email benchmarks disagree by a factor of about 4.6 (FER calculation: 3.43 divided by 0.74). Instantly puts the average reply rate at 3.43%. Smartlead says its median sender gets one reply per 135 people contacted, or 0.74%. Both companies sell cold email software, and both are reporting what happens on their own platforms.
