The term "update field" refers to a type of step that can be incorporated into your drip campaign.
The update field step is unique as it allows you to change a subscriber record based on behavior in the drip. Update Field will add a value to a contact’s demographics or add them to a category defined in the step.
Drag the Update Field element over to the desired section of your workflow. Click the pencil to set your update specifications:
In the example seen above, we update the Rewards Level contact field if a subscriber clicks to share our mailing to Twitter. We could have also placed them into a new or existing category.
