How do I send a large volume of messages through Facebook?

It is easy to send messages in high volume by first clicking on the “To” box and then beginning by typing out the name of the friend. As soon as the name appears under the text box, it is important to add it to the list. Next, type in the name of the second recipient and repeat the process until all the intended recipients are listed out. It is possible to send out multiple messages to around 20 people at a single time.
