Paid messages seem akin to an advertisement, but Facebook says it envisions other scenarios as well. "For example, if you want to send a message to someone you heard speak at an event but are not friends with, or if you want to message someone about a job opportunity, you can use this feature to reach their Inbox. For the receiver, this test allows them to hear from people who have an important message to send them," Facebook writes.
The feature is limited to person-to-person messages, meaning that Facebook business pages and accounts are not able to utilize this service. Paid messages are also limited to one per week to users involved in the trial.
