Last update: May 12, 2026

Marketo Engage has built-in Smart Lists that are useful for common segmentation tasks.

  1. Go to the Database.

  2. Open the System Smart Lists folder to reveal the collection.

  3. To see one example: Select All People, then click the People tab.

    note
    NOTE
    The filters in System Smart Lists do not need to be applied to each Smart List/Campaign. Their contents are automatically recognized.

The following is 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.
NOTE
System Smart Lists cannot be deleted. With the exception of the Possible Duplicates list, they cannot be edited, either.
