You have enabled the Promo Bar in Conversion Kit, but no bar appears on your site.
Why this happens. The Promo Bar tool is a container and ships empty. Enabling it only makes it available. The bar appears only when at least one campaign exists and is active.
What you can do. Create a campaign in the Conversion Kit admin. For the campaign, set a headline, optional supporting text, a button label and link, start and end dates, and the pages it targets.
The tool’s own settings control defaults such as top or bottom placement, sticky behavior, and how long a dismissed bar stays hidden.
