This might be a boon or a bane for you but an upcoming Facebook Messenger feature will give you access to messages from people you aren’t Facebook friends with. Before, when you get messages from people you aren’t friends with, these messages get relegated to the Other section of your inbox. You also don’t get notifications for these. The new Message Requests feature will have these messages show up on Messenger as a message request. You can read the message and choose to respond to it or not, without the other person knowing. If you use Facebook to network, this might help you out. The feature is rolling out in the coming days.
