How to use the filter "Insert Text"
The Insert Text filter can be used to add text either to the beginning of the end of a section of text. To add the "Insert Text" filter, click "Add Text Filter", "Replace, Remove & Insert" then "Insert Text".
The filter provides two options, "In front" or "At the end". In the example below, the name John Doe is added at the end of the text via a filter. Keep in mind the text defined cannot be updated on a per email basis and will apply to all emails matching the rules criteria.
