# Types of Blacklist

There are two types of blacklists available:

* **Blacklist by SMTP:** This option allows for the creation of separate blacklists for each SMTP subaccount, enabling precise management of address blocking for different subaccounts.
* **Blacklist for all SMTP accounts:** This option creates a single global blacklist for all SMTP subaccounts, facilitating centralized management of blocked addresses.

Choosing the appropriate type of blacklist allows for better control over the scope of blocks in accordance with the needs of a specific campaign or account.
