How to DM on the mobile app If you're DMing someone with the app, then first things first, you'll need to make sure the Twitter app is downloaded on your phone and that you are logged in.

To send a direct message on Twitter, go to messages, start a new message, enter the name of who you wish to message and then type and send your note.

Twitter is helping to ensure that you never embarrass yourself by tweeting instead of DM-ing again. At least in the app.
