Nuke Suite allows you to create notifications campaigns. To create a Facebook notification campaign, choose a live application, a segment (optional), and add the message you want to send to the user, along with the dates for the beginning and end of the campaign.

The number of notifications you can send per day is limited, so the selection of your notification campaign can limit the total number of notifications you can send.
