Email data quality metrics and benchmarks:

• Hard bounce rate - Should remain below 2% with proper validation
• Soft bounce rate - Typically 0.5-1% from temporary delivery issues
• Spam complaint rate - Must stay below 0.1% to maintain deliverability
• Invalid email percentage - 5-10% of collected emails contain errors
• Role account prevalence - 2-5% of B2B lists use generic role addresses
• Annual decay rate - 20-30% of emails become inactive each year

List hygiene practices that maintain first-party data quality:

• Regular validation - Verify addresses quarterly to catch changes
• Double opt-in confirmation - Ensure addresses are active and owned
• Engagement-based pruning - Remove chronically inactive subscribers
• Suppression list management - Honor unsubscribes and complaints immediately
• Bounce monitoring - Quickly remove hard bounces to protect sender reputation

OpenSend Revive automates the email validation challenge by replacing bounced emails with active addresses for the same users. The platform matches outdated emails with new active addresses automatically, syncing with your ESP to prevent churn and restore lost customer connections without manual data cleanup.
