How does Validity modify ARF reports, and what impact does it have on identifying recipients for list removal?

Summary

Validity redacts recipient addresses in ARF reports to comply with privacy regulations, making it difficult to directly identify complainers for list removal. While experts debate the extent of Validity's modifications versus those of ISPs, the consensus is that relying solely on ARF reports for list hygiene is no longer sufficient. Email marketers recommend using alternative methods like encoded fields, custom feedback loops, and proactive list hygiene practices (double opt-in, easy unsubscribe). Even with redaction, aggregate complaint data remains valuable for identifying email program issues and improving overall deliverability. Smaller senders need to closely monitor engagement metrics to compensate for reduced data availability.

Key findings

  • ARF Redaction: Validity redacts recipient addresses for privacy.
  • Identification Difficulty: Direct identification of complainers from ARF reports is limited.
  • Alternative Tracking: Encoded fields and custom feedback loops are recommended for tracking.
  • Aggregate Data Value: Aggregate complaint data helps identify email program issues.
  • Proactive Hygiene: Double opt-in and easy unsubscribe improve list health.
  • Engagement Importance: Engagement metrics are crucial, especially for smaller senders.

Key considerations

  • Data Source Shift: Move beyond solely relying on ARF reports for list hygiene.
  • Implementation Effort: Implement encoded fields or alternative feedback loops.
  • Monitoring Needs: Closely monitor engagement metrics and seek subscriber feedback.
  • Deliverability Focus: Focus on overall email program quality and deliverability improvements.
  • Privacy Compliance: Ensure compliance with privacy regulations when implementing tracking.

Validity modifies ARF reports by redacting recipient addresses to protect privacy. This redaction impacts the ability to directly identify complaining recipients for list removal based solely on ARF data. Email marketers suggest using alternative methods for identifying complainers, such as encoded fields, custom feedback loops, and proactive list hygiene practices like double opt-in and easy unsubscribe options. Smaller senders need to be extra vigilant in monitoring engagement metrics to compensate for reduced data.

Key opinions

  • ARF Redaction: Validity redacts recipient addresses in ARF reports, limiting direct identification of complainers.
  • Aggregate Data: ARF reports still provide valuable aggregate data about spam complaints for identifying email program issues.
  • Encoded Fields: Using encoded or hashed fields in email headers allows tracking recipients even with redaction.
  • Alternative Feedback Loops: Implementing custom feedback loops can help identify and manage complainers.
  • List Hygiene: Proactive list hygiene practices, such as double opt-in and easy unsubscribe, are crucial due to redaction.

Key considerations

  • Data Limitations: Relying solely on ARF reports for list hygiene is no longer sufficient.
  • Engagement Metrics: Closely monitor engagement metrics and proactively seek feedback from subscribers.
  • Size Matters: Smaller senders need to be extra vigilant due to the limited data from ARF reports.
  • Proactive Approach: Shift from reactive removal to proactive list management and complaint handling.
