Healthy Growth Benchmarks

  • Net growth rate: 2–5% monthly is strong for B2B; 5–10% for consumer
  • Churn rate: Under 2% monthly is healthy; above 5% signals content or frequency issues
  • Hard bounce rate: Keep below 0.5% of sends to protect sender reputation

A list that grows without engagement optimization leads to declining inbox placement. Balance acquisition with re-engagement campaigns to maintain quality alongside quantity.
