ListManager allows you to exclude those who have received mail recently from receiving the current mailing.
Setting a recency limit for this mailing allows you to prevent recipients from receiving this email if they have received the amount of mail you specify here from any list on the server. In other words, mailings from any list "count" towards the tally of mailings to a particular address.
For example, if joe@example.com received four messages in the past week from list_a, and you set a recency limit for a mailing on list_b to purge recipients who have received more than three mailings in the past seven days, joe@example.com will not receive the mailing to list_b, even though the messages joe@example.com received were from a different list.
By default, this setting will use the list Recency Limit, configured in Utilities: List Settings: Basic Information: Enable Features. You may override these settings on a per-mailing basis using this setting.
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.
