One important stipulation in Facebook’s Promotions Guidelines is that you cannot contact a contest winner via Facebook. This means that you need to collect an entrant’s email address and/or phone number upon entry in order to contact them.
You can collect entrant’s email addresses automatically via Facebook’s Open Graph, but having entrants opt-in by entering their email address manually is the best way to go to avoid being marked as spam.
What is the Facebook Open Graph
The Open Graph is Facebook’s database of user data that includes every Facebook user’s personal information from their age, to who their friends are to which Pages they like. It is also the platform that 3rd party apps connect to in order to pull valuable user data to help businesses target their customers more effectively.How do 3rd Party Apps use the Open Graph?
When a user enters a contest, they will be asked to connect with the contest app in a pop-up window that appears. This pop-up will describe the app, which data will be transferred through the app to the business running the contest, and what the business has permission to do to their account. 2 PermissionsWishpond apps (and most other Contest apps) ask for in this transaction:
