What is bounce ratio tracking?

Bounce ratio tracking monitors list health metrics:

Core metrics:

Total bounce rate: All bounces / messages sent. Hard bounce rate: Hard bounces / messages sent. Soft bounce rate: Soft bounces / messages sent.

  • Segmentation dimensions:
  • By domain/ISP. By list source. By campaign type. By time period.
  • Tracking approaches:
  • Per-campaign measurement. Rolling averages. Trend analysis over time. Comparison to benchmarks.
  • Alerting thresholds:
  • Hard bounce above 2%: Warning. Above 5%: Alert. Sudden spike: Immediate investigation.
  • Use cases:
  • Identify problem list sources. Catch data quality issues early. Demonstrate list health. Guide hygiene priorities.
  • What gets measured gets managed. Bounce ratios quantify list quality.
