It is the partners responsibility to remove plugins and other syndicated content. Zift allows a seven day grace period to remove the content until it becomes blank when you no longer have a Zift subscription.
When it is time for the partner to remove a banner or plugin, the partner can remove the entire page from their site or remove the Zift provided code. Please review the partner page after removing the code and adjust as desired.
If the content is not removed, the content becomes stale and should a prospect interact with the content and/or submits the form, the partner will not be notified.
