The social media-networking giant, Facebook, has said on Thursday that it is currently testing out a new system that would allow users the ability to send mail directly to the inbox of people outside of their friends list. They are charging $1 per message as the company experiments on ways to capitalize on their world-renowned popularity.

Facebook has allowed members to send private messages to those outside of their network, provided of course that their privacy settings are set to default, but, more often than not, these messages are overlooked as they are routed to the "other" folder. According to them, "imposing a fee on the sender may only be the most efficient way of discouraging unwanted messages while facilitating the delivery of more useful and relevant ones."

Only individuals would be permitted this feature if everything turns out well. So a brand such as Toyota or Honda won’t be able to send you automated emails. As of today, Facebook is limiting this service only to a small random group of U.S. users and have set up limits to the number of messages sent in a week.

This comes in a couple of months after Facebook initiated testing a service where users could “promote” their personal posts for added visibility among their contacts for $7 each.
