Pop-up error states "Currently" for a dynamic subject line that uses attributes in Marketing Cloud Email Editor
|Knowledge Article Number||000213658|
When you create an email with a dynamic subject line, the subject line that a subscriber sees is based on the subscriber's attributes according to the rules that you define. If you haven't created profile attributes for your subscribers, the error message will appear.
To resolve this, create a new attribute and then create the dynamic subject line. For instructions to create a new attribute, see How to Create Profile and Preference Attributes. For steps to create a dynamic subject line, see How to Build a Dynamic Subject Line when Creating an Email.
