Why is there a limit for sending messages in Messenger?
Messenger has limits in place to stop messages that people may not want to get, like spam. If you were warned about sending too many messages or sending them too quickly, you'll need to stop sending so many messages or you may be unable to send messages on Messenger.
To learn more about our policies, please review the Facebook Community Standards.
You can only forward a message to up to 5 chats at a time.
