In emails it is possible to hide/display row content based on Row Conditions.
How they work
Display conditions allow you to change the content that is shown to recipient of an email depending on who the recipient is.
To conditionally display the row (content), select the row then either click "Select Condition" to use a pre-built condition or target based on an Audience, or "Add Condition" to enter a Freemarkercondition.
To use existing conditions, click "Select Condition", the following dialog will appear: -
Pre-built conditions created with the Row Conditions feature will appear here along with Static and Dynamic audiences.
To target content to be show only if a customer is in a selected Dynamic Audience, click Audience Dynamic, and then select the Audience to show the content for (i.e. only show this row if the customer is in the selected audience)
Click on the Audience required
After selecting the audience, the row will display the Row Condition in the toolbar
Do not modify the condition (Edit Condition) unless you understand how Freemarker templating works.
