Content personalization - the eye symbol - allows you to specifically adjust the content of your newsletter to specific recipient lists.
This feature is available exclusively in the Drag&Drop-Editor.
You can find the content personalization on the orange frame, which appears when you move your mouse pointer over an element:
You can use the eye symbol at the bottom left to determine which recipients can see this element .
You can filter the recipients by all fields created and filled in your account. In this example, I filter by gender:
I want to display this element to all recipients who have "female" in the "Gender" field and therefore select "the same as".
Alternatively, you can filter by "Existing" (there's something in this field), "Not existing" (the field is empty), "Not the same as" (everything except what you type, and "greater than" and "smaller than" for data and numbers).
An element filtered in this way is now only displayed to those recipients that fulfill the corresponding criterion.
