Get PlayfabIds from a list of emails
You can already send in a list of facebook ids, google ids, steam ids, etc to get back a list of playfab ids. Why not an api like GetPlayFabIDsFromEmails so you can send in a list of emails and get back a list of playfab ids? Right now I can only query 1 email at a time, so trying to query a user's contact list that might have hundreds of emails is impossible.
