These settings determine how frequently inactive members are purged from your database. By default, they are never purged. If you would like to conserve space in your database, you may change these settings.
Purge Held
This setting determines how long someone who has had their membership placed on "hold" should remain until they are permanently erased from the system.
Purge Unconfirmed
This setting determines how long someone who has asked to subscribe to the mailing list, but never "confirmed" their membership should remain in the system until they are permanently erased from the system.
This setting only applies if the mailing list is set to require confirmation from new members. See Utilities: List Settings: New Subscriber Policy: Confirmation.
NOTE: If ListManager is unable to deliver a confirmation email message due to a permanent delivery problem (receiving mail server gives a 500 error), the member will be immediately deleted.
Purge Unapproved
This setting determines how long someone who has applied for membership but not been approved by an administrator should remain until they are permanently erased from the system.
This setting only applies if the mailing list has its security set to "private", so that new memberships require administrator approval. See Utilities: List Settings: New Subscriber Policy: Security.
Purge Expired
This setting determines how long someone who has had their membership expire should remain until they are permanently erased from the system.
This setting only applies if an expiration date is set on memberships, so that memberships expire after a certain number of days. Otherwise, memberships never expire.
Purge Unsubscribed
This setting determines how long an unsubscribed member should remain in the database before they are permanently deleted. Keeping unsubscribed members allows you to get accurate reports of your membership.
Remove Old Referred Members
This setting determines how long referred members are saved before being purged. Referred members are those that have been invited to join your list using the referral tracking feature, but who have not joined the list. Removing referred members does not prevent them from joining the list later; however, it is likely that referred members will be less likely to act on an invitation days or weeks after receiving it. This information should be kept as long as necessary for reporting purposes.
