# Blacklist

The ‘Blacklist’ feature allows for the management of email address blocking by configuring the settings for its scope. This function enables you to adjust at which levels email addresses will be blocked (e.g., globally across the system or only for selected SMTP accounts), aiding in precise management of the recipient list and controlling email deliverability.
