ListManager allows you to exclude those who have received a certain amount of mail recently from receiving more mail. By default, ListManager will send to everyone regardless of how much mail they have received recently. Setting a recency limit for the list allows you to prevent members from receiving email if they have received the amount of mail from any list on the server in the number of preceeding days that you specify here.
You may override these settings on a per-mailing basis on the Mailings: New Mailings: Recipients tab.
Note that by default recency is disabled for all mailings by default. You must set "Enable recency" for one of the types of mailings in order to limit receipt of mail.
Purge email addresses who have received
Specify whether to exclude those who have received more than, fewer than or exactlythe number of email messages specified in this number of mailings.
this number of mailings
Specify the number of mailings that will limit who will receive this mailing. Only mailings will be considered (email messages sent to the list or to subsets), not automated messages (e.g., welcome messages). Mailings from any list on the server will count towards this number.
in this past number of days
Specify the number of days to check for the number of mailings specified.
When a recency limit is specified, ListManager will add an X-LYRIS-Recency header to the mailing that will limit who receives the mailing when actually sent. Example:
X-LYRIS-Recency: match=m,msgs=3,days=7
This sample header limits those who receive more (m) than 3 mailings in the past 7 days. Match options in the header are (f)ewer, (e)qual, or (m)ore than the number of mailings specified.
