A. Initial List Cleaning (Bulk Verification)
Before Sending to Old or Acquired Lists: If you have an old list that hasn't been regularly cleaned, or if you've acquired a list from an event or partnership, a bulk verification is essential before your first send.
After Migrating ESPs: When moving to a new ESP, cleaning your list beforehand can help establish a strong sender reputation with the new provider.
B. Ongoing List Maintenance (Regular Bulk Verification)
Periodic Cleaning: Even with real-time validation, email lists naturally decay (estimated 20-30% annually). Schedule regular bulk cleanings (e.g., quarterly, semi-annually) to remove addresses that have become invalid or unengaged over time.
Before Major Campaigns: Prior to sending out high-stakes campaigns or promotions, a quick list scrub can ensure maximum deliverability and ROI.
