Once you've created your Live Image, you obviously want to be able to share it, typically in your email communications. To do so, simply click the Publish button at the top of the builder.
Once published, click Actions just to the left of the Publish button. Click Export.
In the Export dialog box, input any of the merge tags required to pass through from your ESP, such as name, shipping carrier, or tracking ID, for example.
Next, copy and paste the code into your email template, and you are good to go!
