- The numbers on this page come from SMTP telemetry that Groups.io collects while delivering roughly 15 million real-world emails each day.
- Metrics are updated every five minutes and down-sampled into 5-minute buckets; raw data older than seven days is automatically purged, and roll-ups are kept for 90 days.
