You can only start a conversation with someone who follows you. But Twitter isn’t just a place for individuals only – brands, companies, celebrities, or communities are all on the social network too. That’s why Twitter allows you to customize the options for direct messages, letting you receive messages from anyone, which is colloquially known as open Direct Messages.

Open the app, and locate the three-dot overflow icon or your profile icon. The layout varies between versions, so tap the one you see.
From there, tap on Privacy and content.
Find the option that reads Receive messages from anyone.
Check the box to receive messages from anyone, or uncheck if you only want to get messages from people you follow.
