FeedBlitz has a policy that lists over 5000 subscribers must maintain a minimum 10% open rate, or they will be subject to the automated list purge policy, which will bring the list up to the minimum 10% open rate.
Automated List Hygiene allows you to set engagement standards for your subscribers. When your subscriber becomes inactive, they will be removed from your list and archived, no longer counting toward your subscriber total.
Start at your list dashboard.
Click Settings > List Settings.
On the next screen, click the plus to the right of Automated List Hygiene and then click the No toggle to open the interface.
Set your preferences in the expanded dialogue and click Save Settings to apply your changes and return to the list dashboard.
The Automated List Hygiene feature is available only to FeedBlitz Accel and Enterprise Publishers.
