What happens to the dynamic text, click zones, and other creatives I built before I had Content Builder?
All dynamic text, click zones (now called links) and other creatives that were built prior to Content Builder are still accessible; however, the dynamic text editor is not. You will find your legacy dynamic text files in Content Manager. When you click on a file created with the previous dynamic text tool, it will automatically update and open in Content Builder where you can edit it if desired. If you do not open your old files, they will still show up and be usable in future experiences.
