Blocked people in the Marketo database are marked blocklisted, unsubscribed, marketing suspended, and/or have an invalid or empty email.
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.
In your smart campaign, click on Schedule. Under Smart List Status click on the second link.
People who have reached their communication limits may also be blocked from receiving mails. Learn how to edit communication limits in the Admin section.
The Blocked People tab shows people who might not receive mailings.
Operational emails will be sent to people marked unsubscribed and marketing suspended.
There you go! Now you can be aware of who might not be receiving the mailings.
