Hi Sanna,
I would say the Nurture is the easiest way to do this. You can send an email, wait a day or two, then send notifications to the owner if someone has clicked.
This article has more on Nurtures: http://help.clickdimensions.com/how-to-create-a-nurture-program/
The other way to do this would be through a workflow, but that would be more of an involved set up.
Please let us know if you have any questions!
