Facebook has revised its developer guidelines in order to cut down on unwanted messages to users. Beginning November 9, developers cannot send messages to inactive users who haven’t visited apps within 28 days. In addition, developers must maintain a 17 percent click-through rate on notifications sent to users.
“As an increasing number of developers use notifications, we’ve found that those who focus on sending high quality notifications to active users, as we suggest in our guidelines, are seeing click through rates of 25 percent or higher, which is significantly higher than rates typically seen for other direct response channels such as email,” said a Facebook blog post.
