I have a list of about 130 names that I need to suspend from future marketing emails. Is there a fast way to do this?
Set them to Marketing Suspended or Unsubscribe them Understanding Unsubscribe - Marketo Docs - Product Documentation
Create a simple Smart campaign. In the Smart Filter you can list all email addresses. In the Flow Step you Change Data Value 'Marketing Suspended' to True.
Then Run once.
I would pull up the list you are wanting to change, select all, change data value, and change marketing suspended to "yes". Totally can make a smart campaign for this, but in my opinion, no need to create one for a simple task like this.
