# Blacklist Report

The Blacklist Report provides comprehensive management of blocked email addresses and domains, supporting control over email deliverability. This feature allows users to monitor, add, and remove entries from the blacklist, aiding in the optimization of sends and preventing future emails from being sent to problematic addresses.

Email addresses marked with a Hard bounce status are automatically added to the blacklist. Additionally, users can manually add individual addresses, import entire lists from .csv files, or manage records via the API, enabling flexible and efficient updates to the list of blocked recipients.
