# Validity of Entries on the Blacklist

The validity of blacklist entries is a setting that defines how long email addresses will be stored on the blacklist in the system:

* **No Limit:** Entries remain on the blacklist permanently, with no expiration.
* **From 1 to 6 Months:** Entries are automatically removed from the blacklist after the selected period (ranging from 1 to 6 months).
