After you've created your email script, you'll want to add it to an email to see it in action. Here's how.
Total size of all script tokens inserted into a single email cannot exceed 100KB.
Go to the Marketing Activities area.
Find and select the email you want to add the token to and click Edit Draft.
Double-click the editable area you want to add the token to.
Place the cursor where you want the token to be and click the Insert Token icon.
Find and select the email script token you created previously and click Insert.
That's it! When this email is sent out, the script behind the token will run and populate content.
