A direct message, sometimes referred to as a DM for short, is a private message that can be sent to any person or business through a number of social media platforms. No one else can see these messages aside from the intended recipient. Direct messages from those who are not followers of your business or brand are typically blocked or sent to a separate inbox that you cannot readily access. Brands that want to openly communicate with followers can adjust their direct message settings to receive messages from anyone at anytime.
