Use Built-in/System Smart Lists

Marketo is in the process of changing terms such as Blacklist and Whitelist to Blocklist and Allowlist in our product. During this update, you may see the old terms in our UI and documentation screenshots, and the new terms in our documentation text. We apologize for any confusion.

Go to the Database.
Open the System Smart Lists folder to reveal the collection.
To see one example: Select All People, then click the People tab.

NOTE

The filters in system smart lists do not need to be applied to each smart list/campaign. Their contents are automatically recognized.

Here’s a summary of what the built-in smart lists do:

List Name	Description
All People	All people in your Marketo database
Unsubscribed People	These people can only be sent operational emails; this is usually controlled by the person themselves.
Marketing Suspended	These people can only be sent operational emails; this is usually controlled by you, the marketer.
Blocklist	These people will not receive any email at all.
Bounced Email Addresses	People with an undeliverable email address or that reject your email.
Possible Duplicates	People that might be duplicated in the Marketo database.
