Mail list removal

Mail list removal, also known as list cleaning or list scrubbing, is the process of removing invalid, undeliverable, or unnecessary email addresses from an email list to improve deliverability and reduce bounce rates. Here are some common methods for mail list removal:

  1. Bounce processing: When an email bounces, the email address is marked as invalid and removed from the list.
  2. Hard bounce removal: Hard bounces occur when an email address is invalid or does not exist. These addresses are typically removed from the list immediately.
  3. Soft bounce removal: Soft bounces occur when an email address is temporarily unavailable or has a full inbox. These addresses are often removed after a certain number of failed delivery attempts.
  4. Unsubscribe processing: When a subscriber requests to be removed from the list, their email address is removed.
  5. List hygiene: Regularly reviewing and removing email addresses that are no longer valid, such as those that have been inactive for a long time.
  6. Domain-based removal: Removing email addresses that are associated with domains that are no longer active or have been blocked.
  7. Email address validation: Using third-party services or software to validate email addresses and remove invalid or disposable addresses.
  8. List segmentation: Segmenting the list into different groups based on engagement, demographics, or other criteria to remove unengaged or unresponsive subscribers.
  9. Email address appending: Adding missing email addresses to the list by appending them from other sources, such as social media or customer databases.
  10. List rental or purchase: Renting or purchasing a list from a reputable provider to supplement your existing list and remove invalid addresses.
