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.
