Hey
@Morbane, use the
Tag changer. It allows you do do search and replace for
tags. For non-tag text, you'll need to use
@ELF's suggestion above.
Using the Tag Changer
Go into a Campaign Log and look for the two sideways arrows icons beside "Order by date", print icon, etc.
Click on that and read the instructions.
Make a backup of your Campaign Log (export via the download icon that's beside the Change tag icon) first in case you get unexpected results from your first couple of mass changes.
