The data tells a clear story: most salespeople quit far too early — 70% stop after one email, while 60% of prospects say "no" four times before saying "yes." But the research also shows there's a real ceiling. Reply rates peak at three total emails, and by the fourth follow-up, unsubscribes triple and spam complaints climb. The sweet spot is two to three well-timed follow-ups spaced with a 3-7-7 rhythm, each with a distinct purpose — a bump, a value add, and a graceful close. Speed matters as much as volume: responding within an hour makes you far more likely to reach decision-makers, and half of buyers pick whoever answers first. That's a lot of moving parts to get right on every single lead. If you'd rather not leave it to willpower and memory, Worqd's AI SDRs handle fast follow-up and qualification around the clock — every inquiry answered in under 60 seconds, every cadence tuned to what actually converts.
